Procedure

212 μl of triethylamine (1.52 mmol) and 18.6 mg of DMAP (0.152 mmol) were added to a solution of the compound from Example 57A (200 mg, 0.508 mmol) in dichloromethane (12 ml), and 93 μl of cyclopentanecarbonyl chloride (0.762 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 hydrochloric acid 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: 133 mg (57% of theory)
