Diethyl ether was added to the reaction mixture, which was then washed with 10% aqueous sodium thiosulfate, 1N hydrochloric acid and saturated aqueous sodium hydrogencarbonate in that order. The organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure to obtain the title compound as an orange oil (1.54 g).
