Reaction Steps
The product from Example 62C in chloroform (60 mL) was treated with manganese dioxide (1.45 g, 16 mmol). After refluxing for 12 hours, the mixture was allowed to cool to ambient temperature, filtered and the filtrate concentrated under reduced pressure. The residue was chromatographed on silica gel eluting with 15% ethyl acetate:hexanes to provide the title compound (0.5 g, 42% yield).
