A green chemistry approach for organic synthesis is described here, which involves microwave exposure of reactants in presence or absence of solvents. A novel and simple method has been developed for the synthesis of some benzotriazole derivatives under microwave irradiation. In addition, these compounds were synthesised also by conventional heating procedures for comparison. All the compounds synthesised were characterised by melting point, TLC, IR and 1 H NMR spectroscopy. Comparison between conventional and microwave-assisted synthesis was done by comparing total reaction time and percentage yield. The results suggest that microwave-assisted syntheses lead to higher yields within very short reaction times. On antifungal evaluation by cup plate method, all compounds showed antifungal activity. One compound showed activity similar to and two compounds showed better activity than standard antifungal drug flucanazole.
