Abstract

Procedeu de preparare a 1-(p-metoxi-benzoil)-3-hidroxi-2-pirolidionei cu formula I: (vezi form. în desc.) caracterizat prin aceea ca o 1-(p-metoxi-benzoil)-2-pirolidinona cu formula generala II : (vezi form. în desc.) în care R reprezinta o grupa cloracetil sau trifluoracetil, se tInventia se refera la un procedeu pentru prepararea 1-(p-metoxibenzoil)-3-hidroxi-2-pirolidinonei cu formula I: (vezi formula) compus utilizat în combustie sau profilaxia insuficientei cerebrale, pentru ameliorarea capacitatii intelectuale. Procedeul consta în faptul ca se elimina o grupa protectoare din pozitia 3 pentru a pune în libertate grupa hidroxi si anume trifluoracetilul prin încalzire cu piridina si tiouree în etanol.
