Procedure

Under a nitrogen atmosphere, to a suspension of sodium hydride (60% in oil, 0.24 g) in THF (5 mL) was added a solution of the compound (0.88 g) obtained in step 6 in THF (10 mL) at 0° C., and the mixture was stirred at 80° C. for 6 hr. The reaction mixture was cooled to 10° C., and poured into water. The resultant product was extracted with ethyl acetate. The organic layer was washed with saturated aqueous ammonium chloride solution and brine, and concentrated. The residue was purified by silica gel column chromatography (solvent gradient; 20→33% ethyl acetate/hexane) to give the title compound (0.59 g, 77%) as a colorless oil.
