실험 절차

177 μl of triethylamine (1.27 mmol) and 15.5 mg of DMAP (0.127 mmol) were added to a solution of the amine hydrochloride from Example 62A (200 mg, 0.422 mmol) in dichloromethane (10 ml), and 84 mg of cyclopentanecarbonyl chloride (0.633 mmol) were then added at 0° C. The reaction mixture was warmed to RT and stirred overnight. The reaction solution was washed with aqueous 1 N hydrogen chloride solution and the organic phase was dried over magnesium sulphate, filtered and concentrated under reduced pressure. The crude product was purified by preparative HPLC (RP18 column; acetonitrile/water gradient). Yield: 112 mg (52% of theory)
