BK-MDMA SYNTHESIS EASY AND FAST METHOD.

[K-Cyanide]

@Acidosis Thanks a lot for contribution your synthesis to the forum. I will give it a try; definitely. You write the "precursor is very, very cheap". May i ask what you pay for 1kg and in case there´s no privacy conflict, could you tell us who your supplier is? Thx

 

[chemistry.mob]

there are several vendors on alibaba offering the precursor, but it is not cheap, unless I don't know what "cheap" means to you, they have offered me the substance for more than 150 EURO per kg.
That's just the precursor, then the chemical reagents used in the synthesis also cost money.

380USD with shipping. No tax, or additional fees.

No, I'm not sharing. Not to be a dick. It's because I know how red flags, logarithms and algorithms work. CYA. Cover Your Ass.

It's always "buyer beware", and for a few different reasons.

Scammers, police, customs, loss/breakage, customs/police, loss, delivery "issues", junkies stealing deliveries off the front porch (which is how they can afford your product), using the wrong carrier resulting in 1) loss 2) your package being opened 3) a search warrent resulting in an especially well groomed "delivery person" performing a controlled delivery that results in you eating shitty food in a small concrete room for the next 3-5 yrs or more. Dickheads. "Sneaking and peaking". Peace officer? No one sneaking around spying on others personal business is trying to keep the peace. Now I'm in a pissy mood.

It's pronounced "es-press-o".

I have some doubts about the chemical synthesis of BK-MDMA.
What percentage should dichloromethane, methylamine, ethyl acetate, magnesium sulfate, methylone chlorhidrate and acetone have?
thank you!!

Google "stoichiometry calculator".

I just received 1kg of the precursor (CAS: 52190-28-0) 2-Bromo-3′,4′-(methylenedioxy)propiophenone from a Chinese supplier.
I paid 280 dollars for 1kg with shipping included, from 25kg I will pay 200 dollars per kg with shipping included, it is an expensive precursor, the purity is 99%, the color is brown and the format is small rocks and powder.
it has a strong smell (I don't know what exactly but it's not a bad smell) the format also resembles brown sugar.

 

[Heineken]

this precursor what china seller send is dirty to much brom is inside ...... this precursor need be nice white crystal form but is dirty powder....

 

[Eddybeaumont]

Do you have an address where you can find good precursors? Thanks in advance

 

[Eddybeaumont]

all the ones I found have a brown powder like this

 

[blackburn]

@Acidosis can replace DCM with something else?

 

[xoxoxoxo]

yes u can

 

[arundo]

probably THF, but I didn't try yet.

 

[Wacd75]

I think I found the problem the base does not mix with the HCL I use HCL 33% can you help me please

 

[Acidosis]

Se debe agitar completamente el Hcl para poder mezclarse con la base libre y formar el clorhidrato.

 

[Acidosis]

Hcl must be completely stirred to be able to mix with the free base and form the hydrochloride.

 

[Wacd75]

The fact of not having put MGSO4 could be the cause?

 

[Acidosis]

no

 

[PangeaChemiK]

it is possible use BMK as a precursor instead of 2bromo? For the production price. THANKS

 

[Wacd75]

No

 

[alex12112]

Is it possible to replace DCM (dichloromethane) with toluene DCM?

 

[Acidosis]

Yes, only the freebase is in up layer, dont go to down layer in this time..

 

[alex12112]

I have 33% hydrochloric acid available, is it suitable?

 

[Acidosis]

Idont work any time with 33%,but i think is possible

 

[Eddybeaumont]

I read in the comments that it was possible to replace DCM with IPA. Can you tell me if it is in equivalent quantity? Otherwise, what quantity of IPA is required for this synthesis? Thank you for your answers

 

[BuryVatorynov]

You cant use IPA alkohol

 

[Eddybeaumont]

Thanks

Could be not enough base was added to liberate the all of the methylamine base from the Hcl salt.

Don't ever add Hydrochloride Acid to DCM to to crystallize. I don't care who said what, or who's banging your mom--- it does a shit job as a crystallization solvent when using Hydrochloric Acid. Dry Hydrogen Chloride *gas is a different story, though. But most don't have access to dry Hydrogen Chloride gas.

Yes, you could distill off the DCM (atmospheric or otherwise), but while it does has a lovely smell, it's a carcinogen. You could try a dilute acid extraction from the DCM, and take it from there, or skip DCM altogether.

You got options.
