    Alprazolam (Xanax) synthesis. Small scale.

    Sorry, I know I'm answering my own question but regents not been completely anhydrous shouldn't have any effect on this synthesis, as any traces of water in contact with chloroacetyl chloride would rapidly hydrolyse into HCL gas making them anhydrous. Once an excess of chloroactyle chloride is...

    Alprazolam (Xanax) synthesis. Small scale.

    I've attempted the first part of this synthesis a few times with no success, I keep getting an off white powder mp 118 g 121. In part 1 of this synthesis will traces of water in regents affect success? How important is it to have all regents completely anhydrous? The ammonium acetate I have...

    Alprazolam (Xanax) synthesis. Small scale.

    Well done on this, truly excellent work. I can't get past the first step of this synthesis, I keep ending up with an off white powder MP 118 to 121 which I take is 2-(chloroacetamido)-5-chlorobenzophenone. Have you got any pointers for me of where I could be going wrong please? Your help...

    Alprazolam (Xanax) synthesis. Small scale.

    How many ml of methanol per gram of benzophenone would would you add say 5ml per gram? And how much hexamine? I've attempted the first part of this synthesis a good few times with the same results, an off white powder with m.p. ranging from 118 to 121. I had given up on this synthesis but...
