Reaction Steps

A mixture of 2-(2-((4-fluorophenyl)carbamothioyl)hydrazinyl)-N-methyl-2-oxo-N-(pyridin-4-ylmethyl)acetamide (79) (0.75 g, 2.075 mmol) and sodium bicarbonate (0.35 g, 4.17 mmol) in methanol/water (1:1) (20 mL) was stirred at 80° C. for 26 h. After evaporation of solvent, the residue was extracted with dichloromethane/methanol (10:1) (3×60 mL). The combined organic phase was evaporated and the crude product was purified by flash column chromatography on silica gel (0%-20% MeOH in dichloromethane) to provide 4-(4-fluorophenyl)-5-mercapto-N-methyl-N-(pyridin-4-ylmethyl)-4H-1,2,4-triazole-3-carboxamide (80) as a white solid (0.11 g).
