Reaction Conditions

Temperature	60 °C

Reaction Steps

A mixture of the compound (85 mg) obtained in Example 4, acetyl chloride (18 mg), triethylamine (53 mg) and tetrahydrofuran (2 ml) was stirred at 60° C. for 3 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 recrystallized from ethyl acetate-hexane (2:1, volume ratio) to give the title compound (60 mg) as a colorless powder.
