Reaction Steps

A mixture of 2-bromo-4-ethylsulfonyl-1-fluorobenzene (0.6 g, 2.25 mmol) and sodium methoxide (1.2 g, 22.2 mmol) in THF (20 mL) was stirred at room temperature for 18 h. Water (30 mL) was added and extractive work up with ethyl acetate followed by silica gel chromatography (PE:EA=10:1 to 1:1) gave the title compound (0.5 g, 79.4%) as a yellow solid. 1H NMR (CDCl3, 400 MHz) δ 8.08 (d, J=2.4 Hz, 1H), 7.87-7.84 (dd, J1=8.6 Hz, J2=2.4 Hz, 1H), 7.04 (d, J=8.8 Hz, 1H), 3.99 (s, 3H), 3.11 (q, J=7.4 Hz, 2H), 1.30 (t, J=7.4 Hz, 3H).
