실험 절차

A suspension of 2-anilinopyrimidin-4-carbaldehyde (Method 3; 10 g, 50 mmol) and hydroxylamine hydrochloride (17.4 g, 250 mmol) in EtOH (360 ml) and pyridine (17.4 g, 215 mmol) was stirred and heated at reflux for 1 hour. The reaction mixture was allowed to cool and concentrated to about 150 ml total volume by evaporation. Distilled water (600 ml) was added and the precipitated solid collected by filtration, washed thoroughly with distilled water and dried to give the title compound (9.86 g, 92%) as a white solid. NMR: 6.92 (t, 1H), 7.08 (d, 1H), 7.23 (t, 2H), 7.75 (d, 2H), 7.93 (s, 1H), 8.45 (d, 1H), 9.67 (s, 1H), 12.1 (s, 1H); m/z 215.
