Pentedrone

[Yodaspártai]

Hello, does anyone deal with pentedrone synthesis?

 

[HIGGS BOSSON]

I did this synthesis. The reaction takes place under the same conditions as mephedrone, only use as a precursor 2-Bromovalerophenone

 

[HerrHaber]

Just don't forget to take account of a molar mass increase of 29 with respect to the 2-bromopropiophenone (not the 4'-methylated one)

 

[Yodaspártai]

Thanks

I remember seeing pentedrone synthesis here before, but I can't find it

 

[HerrHaber]

For short: Friedel-Crafts acylation of toluene or benzene with pentanoyl chloride in pressence of anhydrous AlCl3 resulting in aryl n-pentyl-1-one that is brominated on position 2 here you have several options just beware that alpha halogenated ketones are notorious lachrimators, and this is reacted with methylamine prefferably in 2-methyl-pyrrolidone to yield your freebase that is gassed with hydrogen chloride in the nonpolar solvent that was extracted with to form your final crude solid product that is prefferably recrystalized before use. God luck and good speed!

Thank you very much!

Thank you very much!

Yodaspártairemember this is just spilled out of my memory and you should always follow experimented with writeups of procedures only when they are clear to you... as a matter of a fact the brominated intermediate I'm pretty sure I saw here on listings so even if you get the noxious stuff it is already pure enough for you (purifying that is troublesome) and you only need to make the final synthetic step and the salt of it

HerrHaberYes is true like u say made drugs is no so easy if u dont know what u do

StarWarsI exist for people to be motivated in understanding the molecular knowledge before assuming preparative experimentation that can pose a threat to them and even to others... did plenty of silly mistakes myself also but survived and learned from them.

Does anyone know how to synthesize NEP(N-Ethylpentedrone) ?

GermaniumSir, you can ask Mr. Admin,
