実験手順
In a 8 mL sealed vial was mixed N-(4-formylphenyl)isoindoline-2-carboxamide (50 mg, 0.188 mmol) in methanol (1 ml). A solution of O-benzylhydroxylamine hydrochloride (45.0 mg, 0.282 mmol) and sodium acetate (46.0 mg, 0.338 mmol) in water (1.000 ml) was then added and the reaction was stirred overnight at room temperature. The reaction was diluted with water and the product was extracted with dichloromethane. The organic layer was washed with brine, dried with sodium sulfate, decanted, and concentrated. Purification by chromatography provided the title compound. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.55 (s, 1H), 8.21 (s, 1H), 7.65 (m, 2H), 7.50 (m, 2H), 7.44-7.28 (m, 9H), 5.14 (s, 2H), 4.78 (bs, 4H); MS (ESI(+)) m/e 372 (M+H)+.
