실험 절차

Under ice-cooling, 1 g (9 mmol) of methanesulfonyl chloride was added dropwise to a solution of 3 g (8 mmol) of 1-[[[4-(hydroxymethyl)phenyl]carbonyl]amino]cyclohexanecarboxylic acid phenylmethyl ester and 2.46 g (24 mmol) of triethylamine in methylene chloride. After the mixture was stirred at room temperature for 1 hour, 20 ml of 2N dimethylamine-tetrahydrofuran solution was added thereto, and the mixture was stirred overnight. The reaction mixture was distilled off under reduced pressure, and a saturated aqueous sodium bicarbonate solution was added thereto, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried with anhydrous sodium sulfate. The solvent was distilled off under reduced pressure and the residue was purified by silica gel column chromatography to obtain 700 mg (22%) of the title compound.
