Procedure

The product from Example 212a (0.100 g, 0.384 mmol) was combined with iodobenzene (0.375 mL, 3.35 mmol) and copper powder (0.188 g, 2.96 mmol) and the mixture heated in a sealed tube to 218° C. for 90 minutes. The reaction mixture was subsequently diluted with dichloromethane and filtered through celite. The crude product, obtained by concentration under vacuum, was purified by flash chromatography on silica gel (ethyl acetate-hexanes) to give the title compound (0.0847 g, 86
