90 °C

A solution of 3.35 mL (30.0 mmol) 3-chlorobenzonitrile in ethanol (40 mL) was added to a solution of 2.47 g (35.5 mmol) hydroxylamine hydrochloride and 1.42 g (35.5 mmol) NaOH in water (20 mL) at r.t. and then heated at 90° C. for 24 h. After cooling, the reaction mixture was concentrated, the residue diluted with water, followed by filtration and drying to afford 1.13 g (93%) of the title compound. 1H NMR: 8.11 (s, 1H), 7.72 (s, 1H), 7.61 (m, 1H), 7.46 (m, 1H), 7.36 (m, 1H).
