実験手順

A 1M HCl/EtOH solution (50 mL) was added dropwise to the solution of formaldehyde O-benzyl-oxime (3.85 g, 28.48 mmol) in EtOH at 0° C. The mixture was stirred at room temperature for 1 hour, volatiles were removed in vacuo. The residue was dissolved in dichloromethane (100 mL), washed with saturated NaHCO3 solution (75 mL), water (75 mL), and dried over Na2SO4. The product was purified by flash column chromatography using gradient elution from petroleum ether/EtOAc (9:1) to petroleum ether/EtOAc (7:1) to yield O-benzyl-N-methyl-hydroxylamine (1.72 g, 44%). 200 MHz 1H NMR (CDCl3, ppm) 7.40-7.27 (5H, m), 5.53 (1H, br s), 4.71 (2H, s), 2.73 (3H, s).
