Reaction Conditions:
with sodium hydroxide in ethanol;Reflux;
Steps:
3.1.3. Synthesis of 5-(R-amino)-1,3,4-thiadiazole-2-sulfanyl Derivatives (2a-2j)
General procedure: Compounds 1a-1j (0.006 mol) were dissolved in absolute ethanol (20 mL). To thereaction mixture, 1 equivalent of NaOH and 1.2 equivalent of CS2 were added. Thereaction mixture was refluxed for 8-10 h and followed up by TLC. The finished reactionmixture was acidified with 20% HCl, and the precipitates were filtered and purified throughrecrystallization in ethanol.
