A solution of the product of Example 3C (0.130 g, 0.192 mmol) in DMF (6 mL) was treated with diethylamine (1.5 mL), stirred at 25° C. for 1 hour, and partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over MgSO4, filtered and concentrated. The residue was chromatographed on silica gel eluting with a gradient starting with ethyl acetate and ending with methanol to give the title compound (0.52 g, 60% yield).
