After 5 hours, the reaction mixture was diluted with ethyl acetate, washed with saturated aqueous NaHCO3, and brine. The organic layer was dried over MgSO4, filtered, concentrated, and purified on a 12 g column using the ISCO Companion flash system eluting with ethyl acetate to provide the title compound.
