Procedure

The compound (47 mg) obtained in Example 33 was suspended in DMF (2 mL) and to the suspension was added 3-bromopropanol (11 μL) and potassium carbonate(19 mg) The mixture was stirred at room temperature overnight. After addition of water, the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: methylene chloride:methanol=100:0˜10:1) to obtain the title compound (27 mg; 51%).
