Procedure
The product of Example 55B (1.08 g, 0.028 mol) was reacted with osmium tetroxide (0.0007 mol) and N-methylmorpholine N-oxide (4.96 g, 0.043 mol) in a 1:1 mixture of water and THF (50 mL) at room temperature for 18 hours. The reaction mixture was treated with sodium bisulfite and diluted with water. The product precipitated from the aqueous mixture and was collected by vacuum filtration to give the title compound as a a white solid (1.09 g, 93%).
