Thereafter, the reaction solution was diluted with ethyl acetate, and was then washed with water and a saturated saline. The resultant was dried over anhydrous sodium sulfate, and was then concentrated under a reduced pressure. The residue was purified by column chromatography (silica gel 60N, hexane:ethyl acetate=2:1 to 40:60), so as to obtain the title compound (785 mg) in the form of a colorless solid.
