Reaction Steps

To a suspension of 4-(4-methylpyridin-2-yl)benzaldehyde (425 mg) in ethanol (5 ml) was added hydroxylamine hydrochloride (224 mg), and the mixture was stirred at 60° C. for 1 hour. After cooling, the mixture was poured into a saturated aqueous sodium hydrogencarbonate solution and extracted with dichloromethane. The organic layer was washed with water and brine, dried over sodium sulfate and evaporated under reduced pressure to give 4-(4-methylpyridin-2-yl)benzaldehyde oxime (0.43 g).
