Procedure

A mixture of 2-iodobenzyl alcohol (11.0 g), 4-chlorophenylbenzeneboronic acid (8.5 g), and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (800 mg) in Na2CO3 (2M solution, 94 mL) and dioxane (300 mL) was heated to 80° C. for 24 hours. The mixture was cooled, the layers were separated, and the organic layer was condensed. The resulting residue was purified by silica gel chromatography eluting with 20% ethyl acetate in hexanes to give the desired product.
