Reaction Steps

A solution of 5-hydroxy-2-methoxypyridine (1.25 g, 10.0 mmol), 2,3,5-trichloropyridine (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 1.5 hours. The solution was poured slowly into water (200 mL). The precipitate was collected by suction, washed thoroughly with water and dried in a vacuum oven at 45° C., yielding the title compound (2.39 g, 88% yield).
