Abstract

Inventia se refera la un procedeu pentru prepararea formei cristaline alfa-a clorhidratului de 1-(4-amino-6,7-dimetoxi-2-chinazolinil)-4-(2.furoil)-piperazina consta în aceea ca se amesteca sub agitare, la temperaturi cuprinse între 40 tsi 95 degree C un clorhidrat de 1(4-amino-6,7-dimetoxi-2-chinazolinil)-4-(2-furoil)-piperazina sub forma beta sau gama sau un hidrat anhidrat sau solvent al acestuia în dimezilsulfoxid dimetilformamida sau amestecuri ale acestora între ele sau cu solventi alesi dintre benzen toluen cloroform sau tetraclorura de carbon acetona dioxan sau alcooli cu 2....4 atomi de carbon iar forma cristalina alfa a clorhidratatului de 1-(4-amino-6,7-dimetoxi-2-chinazolinil)-4-(2-furoil)-piperazina obtinut se separa, eventual dupa racire.
