The reaction mixture was stirred overnight. Poured into ice water, and extracted with ethyl acetate twice, and washed the organic phase with water twice, brine and dried with anhydrous Na2SO4. The solvents were removed and the residue purified by silica gel chromatograph to give 120 mg of the title compound (28%).
