Pyridine (0.44 ml, 5.43 mmol) and hydroxylamine hydrochloride (75 mg, 1.09 mmol) were added to a solution of 2-([(3,4-difluorophenyl)methyl]oxy)-5-formyl-N-3-pyridinylbenzamide (may be prepared by Example 80; 200 mg, 0.54 mmol) in methanol (10 ml), and the mixture was stirred at room temperature for 30 min. The mixture was evaporated under reduced pressure to half volume. The mixture was diluted with water (20 ml) and filtered. The solid was washed with water (20 ml)/methanol (5 ml) and air dried under vacuum to yield the title compound as a white solid. 167 mg.
