How much desired acid to add at the end?

BigballenPour 10ml acetone onto 1ml concentrated 97%+ sulfuric acid 10:1 ratio. Use pipette or syringe to drop the solution slowly until pH 5.5 is reached. If overacidified, add more freebase, if way overacidified and turns into liquid then to a/b and recryistalize.

You can use a non-polar solvent (ether, benzene, toluene)

yuiopjklI have thought about toulene too but i think the difference of density is too low isnt it ?

I don't think this works. I hope it does and will have to try it.

sandmanI hope you succeed, mate, I failed.

 

[TucoSalamanca.]

have you tried the method using borohydride?

mithyl2Have you done this method

 

[mithyl2]

Have you done this method

TucoSalamanca.I've done the borohydride method many times with no success. the closest i came was making about 0.2% yield of amphetamine. it was real though. i need this to work very badly, and it's driving me absolutely mad. let us know how the dcm goes.

mithyl2I will write, my friend, do not miss your prayers so that this synthesis can be realised, thank you.

 

[TucoSalamanca.]

I couldn't synthesise today, I'll do it tomorrow and report back.

is there any other way for extract than DCM ?
Maybe n-Hexane ?
