실험 절차
To a stirred solution of triphosgene (7.4 g, 0.025 mmol) in dichloromethane (200 ml) at ice bath was added dropwise a solution of 4-methoxy-piperidine hydrochloride salt (10 g, 0.066 mmol) and pyridine (10.9 g, 0.139 mmol) in dichloromethane (100 ml). The mixture was stirred over night and filtered through a silica pad, eluting with dichloromethane and evaporated. After trituration with diisopropyl ether, the mixture was used without purification.
