After the reaction was over, the methanol was removed and the crude product was absorbed in silica gel and purified by column chromatography. The product was isolated in 83% yield as colorless oil. 1H NMR: 3.91 (s, 3H), 6.94 (d, 1H, J=8.4 Hz), 7.01 (t, 1H, J=7.6 Hz), 6.94 (t, 1H, J=8.4 Hz), 7.53 (s, 1H), 7.75 (d, 1H, J=8.0 Hz), 7.53 (s, 1H).
