Reaction Steps

A solution of 5-chloro-2-(2-fluoro-phenoxy)-pyridin-3-ylamine (75 mg, 0.31 mmol), 4-chloro-3-trifluoromethyl-benzenesulfonyl chloride (103 mg, 0.36 mmol), DMAP (20 mg, 0.16 mmol) in anhydrous pyridine (1 mL) was stirred at room temperature for 2 days. The reaction product was separated by preparative HPLC using acetonitrile-water solvent mixture and pure product fractions were lyophilized to provide pure product as a solid. 1H NMR (400 MHz, CDCl3) δ 8.16 (s, 1 H), 7.96 (s, 1 H), 7.89 (d, J=8.0 Hz, 1 H), 7.79 (s, 1 H), 7.62 (d, J=8.0 Hz, 1 H), 7.15-7.13 (m, 3 H), 7.00-6.96 (m, 1 H). MS m/z: 481.0 (M+H).
