Procedure

The compound (188 mg) prepared in Example 15 was suspended in toluene (8 mL) and methyl p-toluenesulfonate (0.32 mL) was added, followed by refluxing for 2 hours. After the reaction solution was air-cooled, an aqueous saturated sodium carbonate solution was added, followed by extraction with ethyl acetate. The organic layer was washed with saturated saline, dried over anhydrous sodium sulfate and then concentrated. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:2→methylene chloride:methanol=85:15) to obtain the titled compound having the following physical properties (122 mg).
