Reaction Conditions:
with sodium hydroxide in water;Reflux;
Steps:
4.5.2. General procedure for the synthesis of 5-substituted-4-phenyl-4H-1,2,4-triazole-3-thiol (3f-3l)
General procedure: Various substituted carboxylic acid hydrazides (25.0 mmol) andphenyl isothiocyanate (25.0 mmol) were dissolved in toluene (30 ml).The reaction mixture was heated for 1-2 h. After completion of thereaction, toluene was evaporated using a rotary evaporator. The resultingprecipitates were filtered, washed with water, and recrystallizedfrom ethanol. Recrystallized thiosemicarbazides 7 was further refluxedwith 4 N sodium hydroxide for 4-5 h. After completion of cyclization,reaction mixture was acidified with dilute hydrochloric acid (adjustedpH 5-6). The resulting precipitates of 1,2,4-triazole-3-thiols 3f-3l werecollected through filtration, washed with water and recrystallized fromethanol.
