実験手順
An ethereal solution of diazodecane was added dropwise to a solution of 100 mg of (13E)-(6RS,9α,11α,15S)-6,9-epithio-11,15-dihydroxyprost-13-enoic acid (prepared as described in Example 2) in 5 ml of methylene chloride at room temperature with stirring until the starting material was not detected by thin layer chromatography on silica gel using a 2% v/v solution of methanol in ethyl acetate as developing solvent. The reaction mixture was concentrated under reduced pressure, and the residue was purified by column chromatography on silica gel using a mixture of cyclohexane and ethyl acetate (1:1) as eluent to give 109 mg of the title compound having the following physical characteristics:
