Introduction

Hydrolysis of BMK glycidate ethers is represented in this topic. The procedure is the same for ethyl (Et) [cas 41232-97-7] and methyl (Me) [cas 80532-66-7] esters of glycidic acid. In case of sodium (Na) salt of this acid [cas 5449-12-7], you can skip first stage of NaOH addition and start from acid hydrolysis. In addition, purification method of obtained P2P is described. This procedure have to be committed to get pure Phenylacetone (P2P) for further syntheses of methamphetamine or amphetamine.

Suppliers of BMK glycidate ethers can be found in BB Listing.

Difficulty rating: 2/10 View attachment 6617

Equipment and glassware:

Reagents:
  • 100 g BMK glycidate ethers (cas 80532-66-7; cas 41232-97-7; cas 5449-12-7);
  • ~20 g NaOH or KOH;
  • ~80 ml HCl (35%) or 100 ml H2SO4 (45%);
  • ~600 mL DCM or Petroleum Ether;
  • ~100 g MgSO4 or Na2SO4;
  • ~500-600 mL Distilled water;
  • ~ 50 g NaCl (optional);

Hydrolysis of BMK glycidates

1. NaOH (or KOH) 20g is dissolved in 250-300 ml distilled water with stirring. The reaction mixture (Rm) have to be cooled to room temperature. BMK glycidate 100 g (methyl or ethyl ester) is added and dissolved completely. Part of BMK is hydrolyzed during this procedure and floated as an oil in the surface of Rm. Rm is stired for 1 h at 75-80 °C with a reflux condenser.
2. Then, 200 ml HCl (35%) or 240 ml H2SO4 (45%) are added in small portions to Rm and heated to 80-90 °C and stired for 3 h. Rm have to be cooled to room temperature, the precipitate is filtered.
3. The reaction solution is extracted with DCM or petroleum ether 3 x 100 ml. Extract is washed with brine to neutral pH 7 several times. Extract is dried with MgSO4 (or Na2SO4) (optional) and filtered from solids.
4. An organic solvent (DCM or petroleum ether) is distilled off to give 65 ml of P2P.

P2P purification

1. The resulting phenylacetone (P2P) is transferred to a round bottom flask with distilled water 1:1 (w/w) and distilled with steam under vacuum.
2. Purified P2P from receiver flask is extracted from water mixture with DCM (or petroleuum ether) 3 x 100 mL. Extract is dried with MgSO4 (or Na2SO4).
3. The resulting solution is filtered from the solids (drying agent) and then an organic solvent is distilled off.

Phenylacetone can be stored long time in a sealed vessel in a freezer. It is recommended to distill it before further syntheses of methamphetamine or amphetamine. Avoid direct sunlight onto phenylacetone and exposure to high temperature

It would be good if we had one like this pmk to mdma

merlinHello, can you ask more clearly please? Do you want to convert PMK glycidate to MDP2P and than to MDMA? There is method on our forum how to get MDP2P. MDP2P -> MDMA. Look around Amphetamines forum section.
Synthesis of MDMA from piperonylmethylketone (PMK) with formamide and LAH
Synthesis of MDMA via Pt/H2 (small scale)

Hello, you can advice our forum topics with better explanation as well. I would be very appreciated. There is method with pictures Complete MDMA synthesis from sassafras oil. There are photos of stages from MDP2P to MDMA and detailed explanation.

Sir, I want to ask, how do we test that the reagents we make are p2p correct.

Can anyone advice on which precursor is best to buy I mean safest to ship to Europe? Is any of the BMK powders legal - where can this be checked? I`m a bit confused as there are quite a few versions available.

P2NP is legal
P2P is restricted
BMK Glycidate 5449 is still quite new and as far as I know not restricted, altho it is common knowledge what glycidates are used for, especially bmk glycidates.

My guess would be that P2NP is the safest bet

1-Phenyl-2-nitropropene, or simply phenyl-2-nitropropene, or P2NP, as it is commonly ... amphetamine class, and are listed as drug precursors in many countries

Bmk salt cas 5449-12-7 is still verry new in de scene it is worldwide allowd and till today not listed in no country.

also prices off P2NP go with the wind I mean not stable prices . the bmk salt is sent from europe with secure shipping line
it cost something like 100€ / kg

P2NP is not restricted so far in most of the countries.

I copy paste from pedia

Yeah the Wikipedia article is actually a little wrong. There are much more usecases for P2NP and it's not restricted

SWIM started with [cas 5449-12-7] after 4h of heating got aqueous layer on top and oily bottom... what did wrong? too much acid?

as far SWIM understands the P2P oily layer should float after reflux and heating? (temperature was constant 90°C. PH1.)

caesare.robotPhenylacetone (P2P) has Density: 1.0057 g/cm3; Hence - your layer heavier than water. It means that it have to be on a bottom. Vice versa, if your water layer is heavier by reason of dissolved salts, p2p layer will be on a top. What is a problem to check boiling point?

This is a very interesting question.
If we cook BMK salts, then the top layer is the p2p
if we now pour this top layer into a measuring cup, and we add warm water. Then the water is the top layer.
