Versuchsvorschrift
4-(Pyridin-2-yloxy)benzonitrile (701 mg, 3.57 mmol) was dissolved in ethanol (14.0 mL), and hydroxylamine (472 mg, 14.3 mmol) was added and the mixture was refluxed for 16 hours. The reaction was cooled to room temperature and then concentrated in vacuo to give the product as a yellow syrup and was taken to the next step without further purification (818 mg, 100%). 1H NMR (500 MHz, CDCL3) δ(ppm): 4.91 (2H, bs), 6.94 (1H, dt, J=8.4, 0.8 Hz), 7.02 (1H, ddd, J=7.2, 5.0, 0.8 Hz), 7.16 (2H, d, J=8.6 Hz), 7.66 (2H, d, J=8.6 Hz), 7.71 (1H, ddd, J=8.2, 7.2, 2.0 Hz), 8.21 (1H, ddd, J=5.0, 2.0, 0.8 Hz). 13C NMR (125 MHz, CDCL3) δ(ppm): 112.1 (CH), 119.1 (CH), 121.4 (CH), 127.6 (CH), 129.0, 139.8 (CH), 147.9 (CH), 152.4, 155.8, 163.4. MS (FAB+): 230 (MH+). HRMS for C12H11N3O2 (MH+): calculated: 230.0930; found 230.0934.
