Procedure

To a solution of sodium cyanide (99 mg) in dimethyl sulfoxide (5 ml), a solution of the compound (605 mg) obtained in Example 249 in dimethyl sulfoxide (10 ml) was added dropwise at 60° C. and stirred at 60° C. for 40 minutes. The reaction mixture was diluted with water and extracted with ethyl acetate-diethyl ether (1:1); thereafter, the organic layer was washed with a saturated aqueous sodium chloride solution, dried with anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent, n-hexane:ethyl acetate=6:4) to give 164 mg of the titled compound (yield, 32%).
