Participants

Reaction Steps

A solution containing the product of Example 10E (1.71 g, 2.3 mmol) in DMSO (3.3 g, 42.3 mmol) was treated with acetic acid (4.1 g, 69 mmol) and acetic anhydride (2.35 g, 23 mmol) at 25° C. for 3 days. Excess ice was added to the mixture which was then made alkaline with 10% sodium carbonate. The mixture was extracted with ethyl acetate, the organic layer was separated, washed with 10% sodium carbonate, water (3×), brine, and dried over sodium sulfate. The solvents were evaporated, and the product was purified by chromatography on silica gel eluting with 30-100% ethyl acetate/dichloromethane to give the title compound (1.1 g, 60% yield).
