Reaction Steps

To a solution of Anisaldehyde (2.0 mmol) in MeOH (5.0 mL), was added K2CO3 (2.2 mmol) and TOSMIC (1.10 mmol) and the reaction was allowed to stir at 80° C. in a sealed vial. 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).
