Reaction Steps

To a solution of 4,6-dichloro-3H-imidazo[4,5-c]pyridine (2.01 g, 10.7 mmol) in DMF (21 mL) at room temperature was added sodium methanethiolate (1.88 g, 26.8 mmol). Mixture was heated at 120° C. for eight hours. An additional 801 mg of sodium methanethiolate was added and mixture stirred at 120° C. for fifteen hours. After adding an additional 340 mg of sodium methanethiolate and heating at 120° C. for five hours, reaction mixture was cooled to room temperature and poured into 100 mL of water. This was then extracted with ethyl acetate (5×150 mL) and combined organic layers were washed with 50% Brine (100 mL), dried (Na2SO4), filtered, and concentrated under reduced pressure to yield 6-chloro-4-(methylthio)-3H-imidazo[4,5-c]pyridine 2.01, which was used in the next step without further purification.
