Reaction Steps
3-Cyanopyridine (4.0 g) and hydroxylamine hydrochloride (3.2 g) were added to a solution of sodium (1.8 g) in MeOH (60 ml). The mixture was stirred 2.5 h at RT and refluxed 30 min. After cooling to RT, solids were filtered off. The solution was evaporated. White crystals (4.7 g) were obtained upon flash chromatography (125 g silica gel; CH2Cl2/MeOH 9:1) followed by a precipitation from heptan and ethyl acetate.
