Reaction Steps
A solution of 5-hydroxy-2-methoxypyridine (1.25 g, 10.0 mmol), 2-chloro-5-trifluoromethylpyridine (1.82 g, 10.0 mmol) and potassium hydroxide (85% pure, 1.08 g, 10.0 mmol) in dimethyl sulfoxide (25 mL) was heated at 90° C. for 2.5 hours. The solution was cooled to room temperature and poured slowly into water (200 mL). After cooling with an external ice-bath, the precipitate was collected by suction, washed thoroughly with water and dried in a vacuum oven at 45° C., yielding the title compound (2.56 g, 95% yield).
