After 2 h, 10 mL of H2O was added to the reaction mixture and it was extracted with ether. The combined organic fractions were washed with sat'd NaCl solution, dried over MgSO4, filtered and the filtrate was concentrated. The residue was purified by chromatography (silica, hexanes:ethyl acetate=4:1) to give the title compound.
