Procedure

A mixture of EXAMPLE 30A (172 mg), EXAMPLE 108A (74 mg), and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (10 mg) in dioxane (6 mL) and 2M aqueous Na2CO3 solution (3 mL) was stirred at 60° C. for 18 hours. The mixture was chromatographed on silica gel using 2-20% ethyl acetate in hexanes to afford the title compound.
