Abstract

L'invention concerne la préparation de 2-(pipérazin-1-yle 4-substitué)-4-amino-6,7-dimethoxy ou 6,7-8-triméthoxyquinazolines. Certaines 2-chloro (ou bromo)-4-amino substitué quinazolines sont amenées à réagir avec la pipérazine 1-substituée correspondante pour former directement les composés désirés ou une 2-(pipérazin-1-yle substitué)-4-(amino substitué)-quinazoline; dans ce dernier cas le substituant du groupe 4 amino de la quinazoline est éliminé sélectivement pour former les composes désirés. Les produits obtenus sont des agents hypotensifs connus. Certains intermédiaires sont nouveaux.The invention relates to the preparation of 2- (4-substituted piperazin-1-yl) -4-amino-6,7-dimethoxy or 6,7-8-trimethoxyquinazolines. Certain 2-chloro (or bromo) -4-substituted amino quinazolines are reacted with the corresponding 1-substituted piperazine to directly form the desired compounds or a 2- (substituted piperazin-1-yl) -4- (substituted amino) -quinazoline; in the latter case the substituent of the 4 amino group of the quinazoline is selectively removed to form the desired compounds. The products obtained are known hypotensive agents. Some intermediaries are new.
