Abstract
Inventia se refera la un procedeu pentru prpararea unor derivati de pirazol cu formula generala I : (vezi formula) în care R, R1 si R2 independent reprezinta halo, alcoxi cu 1...4 atomi de carbon, alchil cu 1..4 atomi de carbon sau hidrogen, cu conditia ca cel putin unul dintre R, R1 si R2 sa fie hidrogen si cu conditia ca R2 sa nu reprezinte hidrogen atunci cand unul dintre R si r1, dar nu ambii, însemna o grupa diferita de hidrogen, R3 înseamna hidroxi, alcoxi cu 1..4 atomi de carbon, alcheniloxi cu 2..4 atomi de carbon. Procedeul consta în aceea ca se hidrolizeaza un nitril cu formula generala II : (vezi formula) în care T, R1 si R2, au semnificatiile de mai sus, cu hidroxizi alcalini în mediul de alcooli alifatici inferiori, la temperatura de reflux.
