Argon gas is bubbled through the mixture for 10 min and bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium (II) (8.3 mg, 0.01 mmol) is added. The mixture is heated at 100° C. for 2 hrs. Then solvents are removed and EtOAc (20 mL) is added. The mixture is filtered to remove any solid and the filtrate is concentrated to give the crude product. Purification by flash column chromatography affords 12.3 mg of the title product.
