The crude mixture was concentrated in vacuo, redissolved in ethyl acetate (100 mL) and washed with water (2×100 mL) and brine (1×100 mL). The organic phase was dried over magnesium sulfate and concentrated in vacuo. The crude product was purified by flash chromatography to furnish 940 mg (24%) of the title compound as a black oil. 1H NMR (500 MHz, CDCl3): 3.02 (m, 4H), 3.84 (m, 4H), 4.30 (b, 2H), 6.97 (d, 1H), 7.06 (d, 1H).
