Desired schiffs bases were prepared by reacting with selected aldehydes. The nucleophilic addition of NH 2 group of hetero to aromatic aldehydes is not so straight forward and easier due to the presence of N in heterocyclic ring. So different conditions were used to synthesis the target compounds eg. Synthesis of 2amino benzothiazole (Reported methods) 1) One step process for synthesis of 2aminobenzothiazole have been reported using substituted aniline, potassium thiocyanate and bromine in acidic condition at low A convenient method for the synthesis of 2substituted benzimidazoles and benzothizoles offers short reaction times, largescale synthesis, easy and quick isolation of the products, excellent chemoselectivity, and excellent yields as main advantages.
