To a solution of 4 g of Pd(OAc)2 in 100 mL of acetonitrile is added dropwise the crude product from Step 1(5 g) under nitrogen at r.t. After 10 h at r.t., the mixture is concentrated under reduced pressure and the residue is purified by flash chromatography on silica gel eluted with 2:1 hexane/EtOAc to give the title compound.
