Reaction Conditions:

with hydrazine hydrate;sodium hydroxide in ethanol;water at 0; for 17.5 h;Reflux;

Steps:

3.2. Synthesis and Characterization of 2,5-Dimercapto-1,3,4-thiadiazole (1)
To a mixture of hydrazine hydrate (20 mmol) in aqueous solution of sodium hydroxide (12 N)(100 mL) was added carbon disulfide (CS2) (40 mmol) in ethanol (100 mL) at 0 °C with stirring during30 min. Then, the mixture was refluxed for 17 h. After cooling, the mixture was acidified with dilutedhydrochloric acid (HCl) and the solid formed was washed, dried and recrystallized from ethanol affordedyellow needles, Yield 98%; m.p. 160-162 °C (Lit. m.p. 162-164 °C) [25].
