A rapid and efficient base mediated synthesis of 1,3,5-trisubstituted 1,2,4-triazoles has been developed from annulation of nitriles with hydrazines, which can be scaled up to a wide range of triazoles in good to excellent yields. Ammonia gas is liberated during the reaction, and halo, hetero functional groups as well as free hydroxyl, amino are tolerated in this transformation. A variety of alkyl
