Procedure
Sodium periodate (4.2 g, 16.34 mmol) in water (8 mL) was added to the solution of the product of Example 14A (4.01 g, 16.34 mmol) in 2/1 methanol/tetrahydrofuran (60 mL) and the mixture stirred for 1 hour. The mixture was diluted with ethyl ether, washed with water and saturated aqueous sodium bicarbonate, dried over sodium sulfate, filtered and concentrated. The residue was purified by flash chromatography on silica gel (200-300 mesh) eluting with 3/1 ether/ethyl acetate to provide the title compound.
