A large series of 1,2‐diaryl‐benzimidazole and 2‐aryl‐1H‐benzimidazolederivatives were synthesized with slight differences using both microwave irradiation and conventional heating methods. Usually higher yields and time reactions reduction were obtained with the former method. All compounds were assayed for their in vitro ability to inhibit humancyclooxygenases, and most of them showed an encouraging
