Abstract

Inventia se refera la un procedeu pentru prepararea 2,4-diamino-5-(3', 4', 5'-trimetoxibenzil)-pirimidinei cu formula generala I: (vezi formula) prin reactia unui compus cu formula generala II: (vezi formula) în care R este o grupa alchil, avînd 1...4 atomi de carbon cu guanidina. Procedeul consta în aceea ca alfa -(3,4,5-trimetoxi-benzal)-3-metoxi-propionitril cu formula III: (vezi formula) se trateaza cu un etilenglicol monoalchileter cu formula generala IV: (vezi formula) (unde R este ceea ce s-a aratat mai sus) în prezenta metoxidului de sodiu, la o temperatura între 80 si 90 degree C si reactia compusului cu formula generala II astfel obtinut, fara izolare-cu guanidina, în prezenta unui alcanol avînd 4...8 atomi de carbon
