Here I thought we were among professional participants of the drug markets. Synthesis should be shared and peer reviewed as open source as anything else?
Personally I would feel safer knowing at the least chemist are not fucking up batches.

Your posts have been deleted. Let's have some decorum. As for publishing fentanyl synthesis, we will consider it and if we decide to publish it, we would do it.
Its synthesis is really simple. But we think this substance should be eradicated.

I do understand dearly why the sentiment on this particular substance. Not long ago, I lost a close dear friend to this substance, it being used as an adulterant at the time to unsuspecting users.
I was furious at the chemistry, the existence of the substance. But that is like blaming the low level drug distributor or the seeker for their misfortune.
In the drug distribution game, you get to meet people from all walks of life. This is true indeed.
e.g. I became interested in why this particular substance is so prevalent, other than the obvious opium wars continue.
Let us not forget trail blazers like Pickard, whom spent almost all of their lives in prison in order to share a medicine mis used, mis understood.
I again believe eradicating knowledge has never worked and reveals morality which has no place in chemistry.
This is mostly a chemistry forum right?
Lets keep it that way, politics, religion, and personal beliefs are left at the gate breh.
Regardless, thanks for the platform and the consideration to keep the platform pure and true without the tainted politics 99.9% of the rest are plagued with.
We must remember that originally fentanyls where created to save lives and are still used in many types of operation and as a pain killer for people with terminal cancer.
Also, I agreed making in clan labs is quite dangerous even for experienced chemists and some have been found dead by familly members. SWIM has made it several times and twice OD'd, but was lucky because SWIM was not working alone and had naxalone on had.
I don't really want to encourage its synthesis either, but if you are really interested in it there are two good patents out there that explain in detail how to do it. Just a note, when working with high concentrations of basic solutions and heat, make sure you use appropriate equipment because it will chew through glass. Also, the most important thing, even if you or your friends have made several synthesis in the past, please find someone with prior fentanyl synthesis experience to guide you through it.
LD50 = 2mg and this stuff sticks to outter walls of glassware, your clothes, floats in the airs... you can easily expose yourself to small quantities even when you are outside your lab. Its not just making it, but having Good Working Procedures - GWPs (to make it safely).
Final note: knowledge is niether Good nor Evil, it's how we use it. And, if anyone is to go down that road, even after saying how dangerous it is to work with, the worse we can do is nothing and hence we should (as a community) at least give them direction so nobody gets hurt in the process.

I really believe that the information concerning how to synthesize fentanyl and it’s related analogues should be freely available. I have also lost a close friend to a fentanyl overdose, I know quite distinctly how much damage that causes to a family. My opinion is that if the information about how to use good working practices in the lab were made well-known, then the chemists interested in this subject could at least research it safely (but if you’ve been to school for chemistry, then really, this synthesis should be fairly easy and you should already be familiar enough with good working practices in the lab to do so safely). Also, if information about how to correctly dose fentanyl was widespread then there would be far less overdose deaths. This substance isn’t evil, it really doesn’t deserve the reputation it has gotten from our media, it is just a very potent opioid analgesic which needs to be handled with proper care. Evidence shows that when it is properly handled it is extremely useful, and safe, for treating severe pain. I think it was Dioscorides that said “the difference between a medicine and a poison is the dose” and that certainly rings true in this case.
I am familiar with a few different ways to synthesize fentanyl, I have done it before, I know how to do it safely in the lab, and if the moderators would allow it, I would be willing to post a synthesis along with all the necessary lab practices to do it safely.
I don’t believe knowledge should ever be hidden from people, but sometimes they need to prove they at least have good intentions before you share potentially dangerous information with an individual.

You can publish the information, we don't mind that. Just make sure that you give us as much detail as possible about the precautions.
Ok, I’d be happy to do that. I have it written in my notebook so I’ll have to type it up, and I will include extensive information on safe practices in the lab, PPE, and how to handle and dose the substance safely.
It may take me a little while though, I have been pretty busy lately, just started a new job, but I promise I will get to it soon as I have the time
Hedgie, I hope you don't mind, but since you were going down that road, I figure I could add one of the patents related to it's synthesis. If you feel insulted, my appologies.
The EU patent EP2252149A2 entitled A METHOD FOR THE PREPARATION OF FENTANYL. check it out, its straight forward and relatively easy to follow, plus most chemicals are easy to handle. The steps are well defined and anyone with a chemistry background can follow easily.
Here is right out from the patent:
EXAMPLE 2:
In a three neck round bottom flask equipped with mechanical stirrer and water condenser, 15.36 gm (o.lO moles) of 4-piperidone hydrochloride monohydrate and 9.3gm (0.10 moles) of aniline was added. To this mixture, 6.5 gm (O.lOmoles) of zinc and 0.6 gm (0.10 moles) of 90% acetic acid were added. The reaction mixture was stirred at room temperature for 24 hrs and at 50 to 7O0C for 24 hrs. Water was then added to the reaction mixture and filtered. Crushed ice was added to the filtrate and was neutralized with excess of aqueous sodium hydroxide solution. The crude 4- anilinopiperidine was obtained by filtration.
In two neck round bottom flask equipped with condenser 17.6 gms (0.10 moles) of 4-anilinopiperidine obtained from step 1, and 100 ml of 100% sodium hydroxide was added. The reaction mixture was heated up to 14O0C and 18.5 gms (0.1 moles) of 2-phenethyl bromide was then added. The reaction mixture was stirred for 4 hrs. After the completion of the reaction, the reaction mixture was poured in the ice cooled water. The crude product was obtained by filtration and recrystallised from petroleum ether (60 to 8O0C) to give colourless crystals of 4-anihno-N-phenethyl piperidipure fentanyl N-(l-ρhenethyl-4-piperidyl)ρropionanilide). In two neck round bottom flask equipped with condenser pressure equalizing funnel and calcium chloride guard tube, a solution of 28.0 (0.10 moles) of 4-anilino_N- phenethyl piperidme prepared in step II, in 100 ml of dichloroethane was taken. To this solution, 18.5gm (0.20 moles) of propionyl chloride was added drop wise through pressure equalizing funnel with continuous stirring. After the completion of the addition, the mixture was further stirred for 1 hrs. After the completion of the reaction, the reaction mixture was washed with 20% sodium hydroxide solution. The aqueous phase was extracted with 2x100 ml of dichloromethane. The combined organic extract was dried over sodium sulphate and concentrated to give crude fentanyl. The crude product was recrystallised from petroleum ether (60 to 8O0C) to give colourless crystals of pure fentanyl having mp 82 to 830C.

Oh shit, I just remembered, it wasn’t Dioscorides that said “the difference between a poison and a medicine is the dose”, it was Paracelsus...
Well the patent say at least 60% from start to end. On a mole to mole or lets say instead gram to gram, you should get close to 1g of fentanyl per 1g of piperidone HCl .
Starting with 15.36 g piperidone HCl
Fentanyl MW: 336.479 gmol-1 HCl 371,932 gmol-1
0.1 mole = 37,1932 g
60% of that is 22.3g
hope this helps

How easy is it to make fetty? I've been interested in this process for awhile, I'm an addict going on 10 years of addiction and would like to know how due to financial reseans. I am no chemist and I didn't even graduaute hs, that being said if I was able to learn it would help me in more ways then one thank you! 
In fact, (per wikipedia), fentanyl is nearly impossible to manufacture in an illicit lab because it's a notoriously difficult compound to synthesize. In comparison, the production of LSD is easier by multiple factors. The implication being: Chinese fentanyl production occurs in government- or government-sanctioned labs
