Reaction Steps
A solution of 4-(dimethylamino)benzaldehyde (5.0 g), hydroxylamine hydrochloride (2.3 g), and sodium acetate (2.7 g) in ethanol (61 mL)/water (11 mL) is heated at reflux temperature for 1 hour. The mixture is cooled to ambient temperature and partitioned between diethyl ether and water. The aqueous layer is back-extracted with diethyl ether and the combined organic extracts are washed with saturated sodium chloride, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give 2.6 g pure white solid as the product. MS: m/z 165 (M+H)+.
