Procedure

A mixture of the compound (200 mg) obtained in Example 4, chloroacetyl chloride (51 mg), triethylamine (146 mg) and tetrahydrofuran (2 ml) was stirred at 60° C. for 1 hr. The reaction mixture was diluted with ethyl acetate, washed with water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by column chromatography [developing solvent:ethyl acetate-methanol (20:1, volume ratio)] and crystallized from hexane to give the title compound (130 mg) as a colorless powder.
