Reaction Steps
4-(Pyridin-4-yloxy)benzonitrile (293 mg, 1.49 mmol) was dissolved in ethanol (6.0 mL) and hydroxylamine (197 mg, 5.97 mmol) was added. The mixture was refluxed for 3 hours and cooled to room temperature and then concentrated in vacuo to give the product which immediately formed white crystals and was taken to the next step without further purification. A small quantity was purified by column chromatography (Hex/EtOAc 1:8) to give the pure product (323 mg, 94%). 1H NMR (500 MHz, DMSO-d6) δ(ppm): 5.95 (2H, s), 6.24 (2H, d, J=8.0 Hz), 7.56 (2H, d, J=8.8 Hz), 7.84 (2H, d, J=8.6 Hz), 8.02 (2H, d, J=7.8 Hz), 9.81 (1H, s). 13C NMR (125 MHz, DMSO-d6) δ(ppm): 118.0 (CH), 122.1 (CH), 126.7 (CH), 132.6, 139.6 (CH), 142.8, 149.8, 177.4. MS (FAB+): 230 (MH+). HRMS for C12H11N3O2 (MH+): calculated: 230.0930; found 230.0950.
