A mixture of 1-(5-(4-chlorophenyl)pyridin-2-yl)-4,4,4-trifluorobutan-1-one (821.7 mg), O-methylhydroxylamine hydrochloride (656 mg) and pyridine (5.239 mL) was stirred at room temperature overnight, and water was added. The mixture was extracted with ethyl acetate, and the extract was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (842.7 mg).
