Procedure

Under the argon atmosphere, the compound (165 mg) produced in Example 100 was dissolved in DME (2 mL), the solution was cooled to −78° C., and a 0.5M potassium hexamethyldisilazane/toluene solution (0.90 mL) was added. After the mixture was stirred at −78° C. for 20 minutes, a DME (1.5 mL) solution of the compound produced in Example 13 was added dropwise, and the mixture was stirred at the same temperature for 10 minutes. After a temperature of the reaction solution was raised to 0° C., water was added, and the extract obtained by extraction with ethyl acetate was washed with water and a saturated saline, dried with anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=90:10→65:35) to obtain a titled compound (177 mg) having the following physical property values.
