Procedure
Hydroxylamine hydrochloride (13.5 g, 194 mmol) was added to a solution of 3-cyanobenzaldehyde (25 g, 191 mmol) in 75 mL of pyridine and 75 mL of ethanol under N2. This was allowed to stir at room temperature for 14 hours. Water (50 mL) was added with vigorous stirring and an off-white solid precipitated. The solid was filtered through a glass frit and washed with another 50 mL of water. Evaporation of residual water under high vacuum gave 19.2 g (69%) of title compound. 1H NMR (CDCl3) δ: 11.61 (s, 1H); 8.21 (s, 1H); 8.00 (s, 1H); 7.96 (d, 1H), 7.85 (d, 1H), 7.61 (t, 1H).
