After stirring for 1 hour under ice cooling, the reaction mixture was washed with water, saturated solution of sodium hydrogencarbonate, and water, successively, and dried (MgSO4), followed by evaporation of the solvent. The residue was subjected to silica gel (60 g) column chromatography, and eluted with hexane-ethyl acetate (5:1), to give the above-captioned compound as colorless solid. Yield: 1.93 g (97%).
