Abstract

Inventia se refera la un procedeu pentru prepararea unor esteri de acid 2 brom-4 metilimidazol-5 carboxilic cu formula generala I : (vezi formula) în care R este alchil cu 1..10 atomi de carbon si Y este cicloalchialchil cu 3..8 atomi de carbon, în care alchilul are 1..6 atomi de carbon, alchil cu 1..6 atomi de carbon sau alchenil cu 3..6 atomi de carbon. Procedeul consta în aceea ca se trateaza un derivat de imidazol cu formula generala II: (vezi formula) în care R are semnificatiile de mai sus, cu o halogenura cu formula generala III : (vezi formula) în care Y are semnificatiile de mai sus, reactia avand loc în mediu de benzen sau toluen, în prezenta unei amine tertiare, la temperatura de reflux.
