BK-MDMA SYNTHESIS EASY AND FAST METHOD.

[Osmosis Vanderwaal]

I only laugh because the only thing easy about this is the reactions, I looked up that first cas#, and yeah, I guess we are stealing that, JUST LIKE ON BREAKING BAD! I get it now, good one!

 

[Richardrahl]

2-Bromo-3,4-methylenedioxypropiophenone is unregulated most of the world unless you live in florida

Europe

 

[antrax]

yes

Final process from 500g of 2b3'4mp 390g pure Brown cola crystals of BK-MDMA.

 

[antrax]

In chemical synthesis you say that with 500 grams of precursor you get 490 grams of methylone hydrochloride, now you say that with 500 grams of precursor you get 390 grams of crystallized methylone, that is, you lose 100 grams of methylone hydrochloride when you recrystallize the methylone hydrochloride?
looking at the photos of the methylone crystals, it has that color due to impurities, since pure methylone is white, how would you purify those brown-colored methylone crystals?

 

[rothschild33]

2nd batch made, quality is top notch, testers preferred it over the circulating mdma pills.

One issue though is that 50g of 52190 was used and only 7 gr of end product acquired. It may be that we have been using methylamine hcl mixed with sodium hydroxide in the dcm solution, probably too much methylamine gas escaping. 40% methylamine solution is still on the way so yield might improve by then. Haven't been doing extraction from the aqueous layer as well so that explains it too. Would using a magnetic stirrer also lead to inferior output?

Edit: I also end up adding HCl directly into the DCM with freebase solution after drying with sodium sulfate. Should the DCM be evaporated with vacuum then the HCl with acetone be added, how will this lead to a different outcome from the method I have been doing so far?

Another thing I'm curious about, how do you do layer separation with buckets? I understand with smaller amount it can be done with separatory funnel, but with buckets it does seem to be trickier to pull it off correctly.

 

[antrax]

My friend, I hope you're okay, why are you saying that much methylamine gas is escaping? According to the chemical synthesis described in the forum, it says that the container must be opened during all the entire synthesis, so it is normal for the methylamine gases to escape since it will not affect the final product.
Thank you!!

 

[antrax]

Has anyone tried this synthesis? I am afraid of spending money on chemicals and not being successful

 

[Richardrahl]

Honestly just by glacing it looks like the same method for russian 4MMC so it should work...

 

[Sleazy2023]

Hey I’m having trouble getting my free base to turn clear , I’ve washed it several times using h20, still not clear / white . I’ve even used h20 and baking soda still not clear.

can someone give me input .



also I skipped the aqueous layer separation stage and I didn’t add any ethyl acetate.

Finally is magnesium sulfate add to bucket for

 

[Acidosis]

If your free base has already been sprayed several times with water and also with bicarbonate, calmly proceed to salt your free base, it is not completely necessary that it remain immaculate white, if with all your washes they continue to have a darker color, perhaps the error is not It is the cleaning phase, perhaps not all of its precursor has reacted and there are some traces of impurities, but later in the recrystallization phase it will solve that problem. Go ahead, do not get bogged down in that small detail.

 

[Sleazy2023]

Also how many ml of hci & acetone is need for bases. I understand we add until base is ph 5, but it acetone 250ml & hci 250ml ? Are is hci 350ml and acetone 150ml?

 

[Sleazy2023]

What does bicarbonate mean ? How do I bicarbonate .

“perhaps not all of its precursor has reacted and there are some traces of impurities”

If this is the case i would have to let dcm and presscor mix longer with 40% methylamine solution ?

 

[bababy]

Can someone make a video on this?

 

[antrax]

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

 

[antrax]

 

[antrax]

i started with 10 grams of precursor (CAS 52190-28-0) which I dissolved with 50ml DCM, then mixed well by hand with a spoon until precursor was properly dissolved, then added 20ml methylamine 40% aqueous solution to the dissolved precursor and in a very short period after mixing with the spoon by hand 2 layers were formed, I separated the aqueous layer from the base with the help of a pipette and added 6ml of ethyl acetate to the aqueous layer after mixing for a short period of time I added again the aqueous layer that I mixed with ethyl acetate to the base, then I added 10ml of water to the base to wash it and I stirred it until 2 layers were formed, but before adding the water the 2 layers were also formed, after removing the aqueous layer of the base i added 2 grams of magnesium sulphate and let it dry for a while, then i checked the pH and it was 7, then i made a 9ml solution of 35-38% lab grade hydrochloric acid with 1ml of acetone and mixed it well, then I added the solution drop by drop to the base and checked the pH each time, and it was still at 7 and then I added a little more solution and the pH was less than 1, instead it should be 5 ,5. In total I added about 5ml of the solution, and I exceeded the quantity, then I took filter paper, filtered it and supposedly left the methylone hydrochloride dry, then I took a methylone anti-drug test and I think it was not positive, no idea.

 

[rothschild33]

the result you got is in line with what I get, recrystallizing it would help make it look better and eliminate excess HCl. If you are unsure whether it is psychoactive and/or safe, try getting a lab rat and compute the mg/kg.

 

[antrax]

but you can appreciate the color of the drug test, it doesn't seem to be red as indicated for methylone positive, rather brown.

 

[blosuetoday]

Red? I only see that you need brown color and you got it.

 

[PolandoEmingarnte]

how much gram crystal no powder u get form 100g 2b34m ?

 

[antrax]

i don´t know, i got 8,5 grams powder from 10 grams of precursor.

 

[Heineken]

if he made crystal he lost a lot product and is very hard to wash it dirty shit to get nice glass.

 

[antrax]

now I will have to wait several days until crystals form.

 

[Heineken]

normal is 1 day to made crystal

 

[antrax]

I also believe too that my chemical precursor (CAS: 52190-28-0) is impure and dirty.
According to the Chinese supplier, it has a purity of 99%, but I think he deceived me, how can I know, that is, to ask him for some laboratory document, in which he reports that said chemical precursor has that percentage of purity.

 

[acidtobase125]

Hi heineken can I please get from you a contact on some secure encrypted messenger so i can text you on pv ?
