Reaction Steps

5-Bromo-3-(2-methylpyridin-3-yloxy)picolinonitrile (56.9 g, 196 mmol) and pyridine-2(1H)-thione (22.9 g, 206 mmol) were dissolved in DMF (400 mL) and cooled to 0° C. NaH (4.94 g, 206 mmol) was added portionwise and warmed to ambient temperature. The reaction was stirred for 18 hours and then poured into 2.5 L of water and stirred for 30 minutes The solids were filtered to provide 3-(2-methylpyridin-3-yloxy)-5-(pyridin-2-ylthio)picolinonitrile (60.8 g, 190 mmol, 96.8% yield).
