The reaction mixture was cooled to room temperature and solid was filtered off and the filtrate was concentrated. The residue was diluted with ethyl acetate, washed with 1M aqueous potassium carbonate, water, and saturated aqueous sodium chloride, and dried. The solvent was removed in vacuo to yield the entitled compound (260 mg) as an oil.
