실험 절차

In 2 ml of dichloromethane, 123.1 mg (0.703 mmol) of the Boc-aminopropanol obtained in Reference Example 1 was dissolved, and then a DMF solution (1 ml) of 136.0 mg (0.704 mmol) of actarit was added thereto, and 17.1 mg (0.140 mmol) of DMAP and 175.4 mg (0.915 mmol) of WSCI.HCl were added thereto in this order under ice-cooling, followed by stirring overnight while gradually returning to room temperature. Ethyl acetate was added thereto, followed by separation by washing with 5% aqueous citric acid solution, 5% aqueous sodium hydrogen carbonate solution and saturated brine consecutively. After dehydration drying with sodium sulfate, ethyl acetate was evaporated under reduced pressure. The precipitate was purified by silica gel column chromatography to give 203.1 mg (83%) of the titled compound. The structure was identified by 1H-NMR.
