Procedure

The 3[-(3-aminophenyl)[[3-(1,1,2,2-tetrafluoroethoxy)phenyl]methyl]amino]-1,1,1-trifluoro-2-propanol (50 mg, 0.12 mmol) was dissolved in 1 mL of dichloromethane. Triethylamine (20 μL, 0.14 mmol) followed by 4fluorophenyl isocyanate (14.6 μL, 0.13 mmol) were added. The solution was stirred at room temperature for 18 hours. The reaction was 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 26 mg (40%) of the desired N-(4-fluorophenyl)-N′-[3-[[[3-(1,1,2,2-tetrafluoroethoxy)phenyl]methyl](3,3,3-trifluoro-2-hydroxypropyl)amino]phenyl]urea product as a yellow oil, which was greater than 95% pure by reverse phase HPLC analysis. HRMS calcd. for C25H22F8N3O3: 564.1533 [M+H]+, found: 564.1566. 1H NMR(CDCl3) δ3.7 (m, 2H), 4.1 (m, 1H), 4.7 (m, 2H), 5.9 (tt, 1H), 6.6 (d, 1H), 6.9-7.4 (m, 11H), 7.5 (s, 1H), 7.8 (s, 1H).
