SYNTHESIS OF 6-AMINO-2-(p-AMINOPHENYL)-4-PHENYLQUINAZOLINE

A study was carried out on the amination of 6-chloro-2-arylquinazolines.The reaction of p-chlorophenyl- and p-nitrophenyl derivatives gives a mixture of mono- and diamination products with predominance of the monoamino products.The desired diamine was also obtained in the reduction of 6-amino-2-(p-nitrophenyl)quinazoline.

SYNTHESIS AND CRYSTAL STRUCTURE OF 6-AMINO-2-(p-AMINOPHENYL)-4-PHENYLQUINAZOLINE

6-Amino-2-(p-aminophenyl)-4-phenylquinazoline (I), a monomer for the preparation of polymers, has been synthesized and studied by x-ray diffraction.The basic geometric characteristics of the molecule of compound (I) have been established - the small angle between the vectors along the C-NH2 bonds and the coplanarity of the p-aminophenyl ring and the quinazoline rings (dihedral angle 1.0 and 3.3 deg) - and together with available data indicate the possibility of obtaining rigid-chain polymers based on compound (I).
