Results and Discussion: A reaction involving two bond formation was employed for the preparation of 3‚5-disubstituted 1‚2‚4-triazole as nucleobase analog. The hydrazides 2a‚b were allowed to react with the heteroaryl substituted acetonitrile derivatives 1a-c using catalytic amount of K2CO3 and n-butanol as a solvent to afford the disubstituted 1‚2‚4-triazoles 3-7 bearing benzothiazole‚ benzotriazole‚ quinoloxymethyl and benziimidazole ring systems in moderate yields.

Chalcones were synthesized according to the previously described methodology (26). A substituted acetophenone (5 mmol) and benzaldehyde (5 mmol) were dissolved in dry methanol (30 ml) and catalytic amount of sodium hydroxide was added to the above solution. The reaction mixture was stirred for 30 min and then neutralized with 1 N HCl. The products were purified by recrystallization from ethyl alcohol and water. The synthetic procedure and reaction conditions for chalcones are illustrated in scheme
