Procedure

To 1-Benzoyl-3-(5-bromo-3-(phenylthio)pyridin-2-yl)thiourea (25.7 g, 57.8 mmol) and MeOH (250 mL) was added sodium hydroxide (38.6 mL, 116 mmol) and stirred at ambient temperature for 8 hours. Diluted with water (250 mL) and filtered and washed with water. The precipitate was dried in vacuum oven to afford the title compound (19.0 g, 96.5% yield).
