Procedure

To a solution of the compound obtained in Example 30 (3) (0.183 g) in a mixture of tetrahydrofuran (2 ml) and water (2 ml), OXONE (registered trademark) (0.4939 g) was added under ice-cooling and the mixture was stirred for 30 minutes and at 15 to 30° C. for 1.5 hours. A saturated aqueous sodium hydrogencarbonate solution was added thereto, and the mixture was extracted with ethyl acetate, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The resulting residue was separated using silica gel column chromatography (hexane:ethyl acetate=1:1) to obtain 0.1722 g of the desired product.
