Procedure

A solution of 5-chloro-6-isopropoxypyridin-3-ol (Preparation 6, 44 mg, 0.232 mmol), 4-(bromomethyl)-N-[(dimethylamino)sulfonyl]-2,5-difluorobenzamide (Preparation 1, 83 mg, 0.23 mmol) and potassium carbonate (64 mg, 0.47 mmol) in dimethyl sulfoxide (5 mL) was stirred at room temperature for 16 hours. The reaction mixture was diluted with water (20 mL) and acidified to ˜pH 4 using acetic acid (2 mL). The resulting precipitate was filtered, washed with water (20 mL) and dried to afford the title compound as a white solid (32 mg).
