Reaction Steps
To a solution of 2-methoxyphenol (50 g, 402.8 mmol) and triethylamine (84.2 mL, 604.2 mmol) in anhydrous dichloromethane (300 mL), was added methanesulfonyl chloride (37.6 mL, 483.3 mmol) at 0° C. under nitrogen. The reaction mixture was stirred at 0° C. for 2 hours, quenched with ice water (250 mL) and transferred to a separatory funnel. The organic phase was washed with a solution of NaOH (8 g) in ice water (200 mL), brine, dried over Na2SO4, filtered and concentrated under reduced pressure to give the title compound as a colorless liquid (81.44 g, 100%). 1H NMR (400 MHz, DMSO-d6) δ 3.32 (s, 3H), 3.83 (s, 3H), 6.96-7.0 (m, 1H), 7.18-7.2 (m, 1H), 7.27-7.33 (m, 2H).
