実験手順
A solution of 4-dimethylaminopyridine (1.17 g, 11.8 mmol) and 4-(4-methylphenyl)butyric chloride (1.06 g, 5.90 mmol) in toluene (5 mL) was added to a solution of (2R)-1-acetoxy-2-acetylamino-2-ethyl-4-(1-methylpyrrol-2-yl)butane (444 mg, 1.60 mmol) obtained in Reference example 2 in toluene (15 mL) and the mixture was stirred at 110° C. for 72 hours. The temperature of the mixture was returned to room temperature and ethyl acetate and water were added to the reaction mixture to separate it. The thus obtained organic phase was separated, washed with water and a saturated aqueous NaCl solution and dried over anhydrous sodium sulfate. After filtration, the solvent was evaporated under reduced pressure and the residue was purified by silica gel chromatography (ethyl acetate:hexane, 3:2-2:1) to obtain the title compound (377 mg, yield: 40%).
