The alcohol of Example 3(16 g), methylene chloride (300 ml) and pyridinium chlorochromate (14.5 g) were stirred over two days at room temperature. The solution was filtered through a column of Fluorosil using methylene chloride as eluant. Evaporation of the solvent gave 15.8 g, corresponding a 100% yield, of the desired product, which solidified on cooling.
