Reaction Steps

To 5 ml of ethanol were added 0.4 g of sodium bicarbonate and 0.33 g of hydroxylamine hydrochloride, and the mixture was heated to reflux for 1 hour. After allowing to cool, 0.67 g of 3,5-dichloro-4-(2,2,2-trifluoro-1-methylethoxy)pyridine-2-carbonitrile at room temperature, and the mixture was stirred for 4 hours, and concentrated. To the residue was added water, the resultant solution was extracted with ethyl acetate three times, and the organic layers were combined, washed with an aqueous saturated sodium chloride solution, dried with anhydrous magnesium sulfate, and concentrated. The residue was washed with hexane three times to obtain 0.65 g of 3,5-dichloro-4-(2,2,2-trifluoro-1-methylethoxy)pyridine-2-carboxamide=oxime.
