Participants

Reaction Conditions

Reaction Steps

The compound (155.1 mg) obtained in Example 519 was dissolved in dimethyl sulfoxide (5 ml). To the solution, sodium cyanide (127 mg) was added and the mixture was heated at 50° C. under stirring for 10 min. To the resulting reaction mixture, ethyl acetate was added and the organic layer was washed with water twice, dried with anhydrous sodium sulfate and the solvent was distilled off under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent, n-hexane:ethyl acetate=3:1) to give 77.7 mg of the titled compound (yield, 61%).
