실험 절차

To a vigorously stirred suspension of N-methylbenzylamine (0.260 mL, 2 mmol) in EtOAc (3 mL) and 3 mL of saturated NaHCO3 solution was added 1-chloroethyl chloroformate (0.160 mL, 2 mmol). Effervescence was observed. Once gas production had ceased, the reaction mixture was diluted with hexanes (10 mL). The aqueous phase was removed and the organic phase was washed with brine (5 mL), dried and concentrated to give the crude product as an oil (˜0.250 g). The compound was used in the subsequent step without further purification.
