Synthesis of some new 2- [2 [chlorobenzoyl] vinyl] -4H-3, 1-quinazolin-4-one derivatives

ABSTRACT

Several 2-[2-[p-chlorobenzoyl] vinyl] -4H-3, l-quinazolin-4-one derivatives have been synthesized by the reaction of 2-[2-p-chlo-robenzoyl] vinyl]-4H-3,l-benzoxazin-4-one with amino compounds. The action of hydrazines, hydroxylamine hydrochloride, urea, thiourea, and P2S5 have been also investigated
