실험 절차

A solution of (6-bromopyridin-3-yl)(phenyl)methanone, 4-b, (5.2 g, 20 mmol) in 100 ml of 95% ethanol was treated with N-hydroxylamine hydrochloride (4.2 g, 60 mmol) and sodium carbonate (6.36 g, 60 mmol). The resulting mixture was heated at reflux for 3 hours, cooled to room temperature, and concentrated under vacuum. The residue was taken into ethyl acetate (100 mL) followed by washing with water and brine (50 mL each). The organic layer was dried over sodium sulfate and concentrated. The resulting solid was recrystallized in ethyl acetate/petroleum ether to provide the product, 4-c, (2.7 g, 50%). 1H NMR (CD3OD, 300 MHz,): δ 8.34 (s, 1H), 7.78 (m, 1H), 7.32 (m, 7H).
