The solvent was evaporated under vacuum, and the crude was dissolved in ethyl acetate and washed with water. The organic phase was dried (Na2SO4) and evaporated; the crude was purified by flash chromatography with petroleum ether-ethyl acetate (97-3 to 95-5) to give the title compound (1.23 g, 90% yield).
