Reaction Steps

To a solution of N-(2,2-dimethoxyethyl)-N-(2-fluorobenzyl)-4-methylbenzenesulfonamide (DD; 0.6 g, 0.0041 mol) in carbon tetrachloride (15 mL) was added N-bromosuccinimide (1.08 g, 0.00603 mol) followed by AIBN (0.06 g, 0.00041 mol) and heated for 3 h at 80° C. Then carbon tetrachloride was evaporated and the crude was purified by column chromatography to get the title compound. 1H NMR (400 MHz, CDCl3) δ 9.46 (1H, s), 8.80 (s, 1H), 7.97-7.95 (d, J=8.4 Hz, 1H), 7.79-7.74 (m, 1H), 7.35-7.31 (dd, J=8.0, 9.6 Hz, 1H).
