Reaction Steps

To a solution of 2.333 g of (13E)-(9α,11α,15S)-2-phenylseleno-6-oxo-9-hydroxy-11,15-bis(tetrahydropyran-2-yloxy)prost-13-enoic acid methyl ester [prepared as described in Reference Example 8(h)] in a mixture of 22 ml of ethyl acetate and 11 ml of tetrahydrofuran were added 733 mg of sodium bicarbonate and 1 ml of 30% (v/v) hydrogen peroxide at 34° C. and the mixture was stirred at that temperature for 30 minutes. The reaction mixture was then diluted with ethyl acetate, washed with water, an aqueous solution of sodium sulphate, water, an aqueous solution of ammonium chloride and an aqueous solution of sodium chloride, dried over magnesium sulphate and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel using a mixture of cyclohexane and ethyl acetate (2:1) as eluent to give 1.524 g of the title compound having the following physical characteristics:
