A solution containing the product from Example 128B (0.50 g, 0.78 mmol) in DMF (8 mL) was treated with dichlorobis(triphenylphosphine)palladium(II) (0.165 g, 0.235 mmol), and the product from Example 74A (0.60 g, 1.63 mmol), stirred at 100° C. for 6 hours, cooled to 25° C., filtered through celite®, and partitioned between ethyl acetate and water. The organic was washed with brine, dried over MgSO4, filtered and concentrated. The residue was chromatographed on silica gel eluting with 0-15% ethyl acetate in chloroform to give the product (0.322 g, 63% yield).
