Reaction Conditions:

with sodium hydroxide in ethanol;water; for 3 h;Reflux;

Steps:

Synthesis of thiadiazole 1 (1-phenyl-1,3,4-thiadiazole-5-thiol)

To a solution containing 95 % ethanol and 0.1mol of sodium hydroxide (dissolved in the least amount of water), 0.1 mol of thiobenzoic hydrazide was added, followed by 0.15 mol of carbon disulfide. The reaction mixture was heated under reflux for 3 h till all the evolution of hydrogen sulfide ceased. The resulting mixture was diluted with wate rand acidified with diluted hydrochloric acid containing ice.The reaction mixture was allowed to stand at the ice bath for 60 min, filtered, washed with water and recrystallized from methanol .
