Reaction Steps
To a solution of hydroxylamine hydrochloride (0.47 g, 7.0 mmol) in methanol (10 mL) was added sodium metal (0.16 g, 7.0 mmol) portionwise. After all the sodium metal had dissolved 4-cyano-2-dimethylaminopyridine (1.0 g, 7.0 mmol) was added and the reaction was heated to reflux for 4 hours. The reaction was cooled to room temperature, filtered to remove precipitated sodium chloride and the filtrate was evaporated to dryness. The residue was dissolved in ethanol in order to crystallise the product but this was unsuccessful, so the solvent was removed in vacuo to give the title compound as a white solid (1.7 g), which was contaminated with ethanol.
