Procedure
A solution of m-toluenesulfonyl chloride (0.53 g, 2.78 mmol) and 2-methoxy-4-methylphenol (0.38 g, 2.75 mmol) in DCM (10 mL) was treated with triethylamine (0.5 mL,3.6 mmol) and stirred at ambient temperature. After 18 hours the reaction was concentrated in vacuo, the residue dissolved in 1:1 hexane:DCM, filtered, and the filtrate evaporated under high vacuum giving the title compound as a white solid (0.79 g, 99%). 1H NMR (300 MHz, CDCl3) δ 7.72 (br s, 1H), 7.66 (br d, 1H, J=7.2 Hz), 7.45 (br d, 1H,1J=7.2 Hz), 7.38 (t, 1H,=7.6 Hz), 7.00 (d, 1H,=8.1 Hz), 6.67 (m, 1H), 3.54 (s, 3H), 2.42 (s, 3H), 2.31 (s, 3H).
