Procedure

The 3-[(3-aminophenyl)[[3-(1,1,2,2-tetrafluoroethoxy)phenyl]methyl]amino]-1,1,1-trifluoro-2-propanol from EX-528C (50 mg, 012 mmol) was dissolved in 1 mL of dichloromethane. Triethylamine (25 μL, 0.18 mmol) followed by 4-fluorobenzene-sulfonyl chloride were added. The solution was stirred at room temperature for 5 hours, at which time HPLC analysis indicated that no free amine starting material remained. The reaction was quenched with water and filtered through pre-wetted celite eluting with ethyl acetate. The solvent was evaporated, and the residue was purified by reverse phase HPLC eluting with 10% to 90% acetonitrile in water to afford 20.1 mg (29%) of the desired 4-fluoro-N-[3-[[[3-(1,1,2,2-tetrafluoroethoxy)phenyl]methyl]-(3,3,3-trifluoro-2-hydroxypropyl)amino]phenyl]benzenesulfonamide product as a yellow oil, which was greater than 98% pure by reverse phase HPLC analysis. HRMS calcd. for C24H21F8N2O4S: 585.1094 [M+H]+, found: 585.1083. 1H NMR (CDCl3) δ3.6 (m, 2H), 3.8 (dd, 1H), 4.3 (m, 1H), 4.6 (s, 2H), 5.9 (tt, 1H), 6.4 (d, 1H), 6.5-6.6 (m, 3H), 6.9-7.4 (m, 7H), 7.6 (m, 1H).
