The mixture was stirred at 100° C. for 6 h. After cooling to RT, the mixture was diluted with EtOAc, washed with water and brine. The organic layers were dried over Na2SO4, filtered, and concentrated. The residue was purified by chromatography on silica gel with EtOAc in methylene chloride (0-50%) to afford the desired product.
