Synthesis and pharmacological investigation of novel 4-(2-methylphenyl)-1-substituted-4H-[1,2,4]triazolo[4,3-a]quinazolin-5-o nes as new class of H1-antihistaminic agents

A series of novel 1-substituted-4-(2-methylphenyl)-4H-[1,2,4]triazolo[4,3-a]quinazolin-5-o nes were synthesized by the cyclization of 2-hydrazino-3-(2-methylphenyl)-3H-quinazolin-4-one with various one carbon donors. The starting material 2-hydrazino-3-(2
