The reaction mixture was then stirred at room temperature for 16 hours. The reaction mixture was concentrated, and the residue was chromatographed on silica gel eluting with 10-20% ethyl acetate/hexane to yield the title compound. 1H NMR (300 MHz, CDCl3) δ ppm 8.18 (s, 1H), 8.06 (d, J=7.54 Hz, 1H), 7.67 (d, 1H), 7.56 (t, J=7.73 Hz, 1H), 4.72 (m, 2H), 2.48 (m, 3H).
