实验步骤: 4-Methoxy-3,5-dimethylbenzaldehyde (1.86 g, 11.3 mmol) was dissolved in ethanol (30 mL) and stirred with hydroxylamine hydrochloride (2.4 M aq. solution, 5.65 mL, 1.2 eq.) and Na2CO3 (1.2 M solution, 5.65 mL, 0.6 eq.) at room temperature for 2.5 hours. The mixture was then heated to 60° C. and additional hydroxylamine hydrochloride and Na2CO3 was added. The mixture was again stirred overnight at 60° C., transferred to a separatory funnel, diluted with EtOAc. The organic layer was separated, washed with brine, dried over MgSO4, filtered and concentrated. The product was purified by ISCO chromatography with EtOAc/hexanes eluent to yield 1.55 g (8.56 mmol) of 4-methoxy-3,5-dimethylbenzaldehyde oxime as a white solid. M+1=180.0. transferred to a separatory funnel The organic layer was separated washed with brine dried over MgSO4 filtered concentrated The product was purified by ISCO chromatography with EtOAc/hexanes eluent
