Abstract

A large number of pyridazinone derivatives were reported to exhibit insecticidal [1–5], herbicidal [2, 6], antiallergenic [7], antihypertensive [8], analgesic [9], anti-inflammatory [10], and bacteriocidal activities [11]. This prompted us to synthesize a new series of heterocyclic pyridazinone derivatives through the reaction of 4-(p-bromophenyl) or 4-(p-methylphenyl)-4- oxo-2-butenoic acid 1a, b [12] with benzylamine in dry benzene and yielded the addition ...
