실험 절차

N,O-dimethylhydroxylamine hydrochloride (5.41 g, 55.5 mmol), EDC (12.77 g, 66.6 mmol), followed by triethylamine (17 mL, 122 mmol) were added to a cooled 0° C. solution of 3-(4-methoxyphenyl)propionic acid (10 g, 55.5 mmol). The reaction mixture was stirred for 15 h under N2 and then concentrated. The residue was partitioned between 1 N HCl and EtOAc. The organic layers were washed with saturated NaHCO3, brine, dried over Na2SO4 and concentrated to an oil. The oil was purified by silica gel chromatography (40% EtOAc in hexanes) to give a clear oil (10.6 g, 85%).
