Tetrakis(triphenylphosphine)palladium(0) (54 mg, 0.047 mmol) was added and the mixture was heated to 110° C. for 5 hours. Solvent was removed in vacuo and the residue was dissolved in MeCN, filtered, and purified by flash chromatography, eluting with a gradient from 0-40% EtOAc in hexanes. Yield: (67 mg, 44%). LCMS (M+H)+: 325.9.
