A mixture of Example 86a (0.136 g, 0.5 mmol), aniline (0.186 g, 2.0 mmol), and 60% sodium hydride (0.12 g, 3.0 mmol) in dioxane (2 mL) was stirred and heated at 60° C. for 16 hours. After cooling, the reaction mixture was partitioned between water and ethyl acetate. The aqueous layer was neutralized with 10% HCl and extracted with additional ethyl acetate twice. The combined organic layers were washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, filtered, and concentrated. The residue was purified by flash chromatography on silica gel (2:3 ethyl acetate/hexanes) to give 0.095 g of the title product.
