Reaction Steps

To a solution of t-butyl 2-(2-bromo-4-((methylamino)methyl)phenoxy)acetate (2) (4.4 g, 13.4 mmol, 1 eq) in DCM (50 mL) was added 2,6-lutidene (3.1 ml, 26.8 mmol, 2 eq) and 4-fluorobenzenesulfonyl chloride (2.9 g, 14.7 mmol. 1.1 eq, Aldrich, Milwaukee, Wis., USA). After the mixture was stirred for 18 h at room temperature, it was washed with 1 N HCl (100 mL), saturated NaHCO3 (100 mL), and brine (100 mL). The washed DCM layer was dried over Na2SO4 and concentrated in vacuo. Silica gel purification (linear gradient of 0% EtOAc/hexanes to 100% EtOAc/hexanes) of the resultant residue yielded 2.95 g (44.8%) of t-butyl 2-(2-bromo-4-((4-fluoro-N-methylphenylsulfonamido)methyl)phenoxy)acetate (3) as a white solid. 1HNMR (CDCl3, 300 MHz): δ 7.82 (m, 2H), 7.44 (d, 1H), 7.22 (m, 3H), 6.72 (d, 1H), 4.57 (s, 2H), 4.04 (s, 2H), 2.58 (s, 3H), 1.46 (s, 9H).
