Hello everyone! I'm new here. I'm just a beginner hobbyist who wants to enter the world of chemistry.
I would like to know if any of you know any way to synthesize the a-pvp precursor substances (for example: 48% hydrobromic acid, pyrrolidine and valerophenone). since in my country it's quite difficult to obtain, the other thing is to buy online abroad, but since they are controlled substances it is much more difficult to get them.
any opinion or help would be welcomed!

opinion :- @Rutherford as you are new to world of chemistry my advice will be to start from basic just buy a lab manual, basic equipment and there are infinite lectures on youtube at least make your basics clear otherwise you are Dead before completeing your first synthesis.

help :- you just can't make everything in your backyard if you are making something illegal you have to buy something illegal.

just don't kill yourself.

HEISENBERGhe want's😐 to make 48% hydrobromic acid, pyrrolidine and valerophenone in his backyard.

Rutherford2HBr+H2O2=Br2 + 2H2O, its work good but importan good acid balance, if low or high reaction stop

HBr - just mix some KBr or NaBr with dilute sulfuric acid (about 30-40%) and distill everything between 122-127C. You will obtain 40% HBr (about 1,38 g/ml density). Use excess of sulfuric acid (about 1.5-2.0 times more moles). Use only dilute H2SO4 because if you don't you will make few mls of Br2 (bromine) which distills around 55-60C and this is a big problem. Avoid at all cost substance for amateur chemist as it STINKS JUST... SO MUCH.

pyrrolidine -
Also my advice for you - always look for synthesis videos and all kind descriptions of synthesis before you ask question on this or any other scientific or "scientific" forum. People doesn't like asking without searching on your own. Also try to provide your interesting thoughts. And don't write dumb things.

Valerophenone - unfortunatelly there is no way to do it without hard to obtain or work with chemicals. You just have to make valeryl chloride using thionyl chloride or cyanuric chloride. There are ways around it but they are just don't wort it as they are either expensive or unimaginable hard to follow.

Rutherfordhi.im new as well i admire your courage to just throw that thought out there.i dont feel im qualified to give you advice,im a small fish in a big pond.i would"""" start"'''by getting real acquainted with everything needed.i dont know what ur back ground might be?my goal is the same.i have been able to get everything here at my location.i have not opened a single bottle yet!im smart as hell but not a chemist by schooling.i have spent the last month cramming msds data sheets and wikipedia in a bad kinda way.another 6months of study, i may be close to open bottles....laugh....i think the best advice i could say to you is: baby steps man.wish i could offer more than that,good luck.....

You can make HBr from NaBr or KBr is lots of tutorials on youtube
