A solution of ethanol (5.0 mL), benzonitrile (203 mg, 1.97 mmol) and hydroxylamine (520 mg, 7.87 mmol) were refluxed for 1 hour. The reaction was then cooled to room temperature and concentrated in vacuo to give the a clear oil which was taken to the next step without further purification (268 mg, 100%). 1H NMR (500 MHz, CDCL3) δ(ppm): 4.92 (2H, bs), 7.38-7.44 (3H, m), 7.62-7.65 (2H, m). 13C NMR (125 MHz, CDCL3) δ(ppm): 126.1 (CH), 128.9 (CH), 130.2 (CH), 132.6, 152.8. MS (FAB+): 137 (MH+). HRMS for C7H8N2O (MH+): calculated: 137.0715; found 137.0718.
