Reaction Steps

A solution of N-[(1,2,3,4-tetrahydronaphthalen-2-yl)(aminothiocarbonyl)amino]formamide (0.6 g, 2.4 mmol) in 10 mL of 10% sodium hydroxide was heated at 70° C. for 30 minutes. The solution was cooled, acidified with dilute. hydrochloric acid and extracted with ethyl acetate. The ethyl acetate extract was washed with brine, dried over sodium sulfate and concentrated. The residue was recrystallized from ethyl acetate/hexane and filtration gave 2-(1,2,3,4-tetrahydronaphthalen-2-yl)-2,4-dihydro[1,2,4]triazole-3-thione (0.25 g. 1.06 mmol), m.p. 200.5° C.
