The reaction mixture was partitioned between ethyl acetate and sodium hydrogen sulfate, the organic layer was washed with sodium carbonate, brine, dried and concentrated under reduced pressure. The crude mixture was purified by flash chromatography on silica (eluent 1 to 10% ethyl acetate in dichloromethane) to yield 0.027 g (39%) of the title compound as a colourless solid.
