실험 절차

In the illustrated reactions, the compound of Formula II is prepared by reacting hexahydro-1,4-diazepine with furoyl chloride in an acid solution. The resultant 1-(2-furoyl)-hexahydro-1,4-diazepine is hydrogenated to produce 1-(tetrahydro-2-furoyl)-hexahydro-1,4-diazepine which is reacted with 2-chloro-4-amino-6,7-dimethoxyquinazoline in the presence of methoxy ethanol to give the compound 2-[4-(tetrahydro-2-furoyl)-hexahydro-1,4-diazepinyl-1]-4-amino-6,7-dimethoxy quinazoline. The hydrochloride salt is prepared by acidifying with hydrogen chloride.
