실험 절차
To a stirred suspension of 6-methoxy-2,3-dihydro-1H-inden-1-one (15.0 g, 93.0 mmol) and Et3N (28.2 g, 279 mmol) in MeOH (200 mL) was added NH2OH.HCl (12.8 g, 186 mmol) at room temperature. After the addition, the resulting solution was stirred at room temperature for 24 hours. The reaction mixture was concentrated under vacuum. To the residue was added EtOAc (300 mL). The solution was washed with water (2×150 mL), brine (150 mL), dried over Na2SO4, and concentrated under vacuum to give (1E)-N-hydroxy-6-methoxy-2,3-dihydro-1H-inden-1-imine (1a, 17 g, >100%) as a white solid.
