New heterocyclic compounds containing pyrazol‐5‐one coupled with benzimidazole, benzothiazole, benzoxazole, quinoline, naphthyridin, and pyrazole were synthesized. Comparative investigations to synthesize these interesting classes of heterocyclic compounds through conventional heating or undermicrowave‐irradiation conditions were presented. Synthesized compounds 1a, 2a, 4k, 3a, c, 5a, b, 6b, 7a, b
