Procedure

A solution of 3-[[3-(4nitrophenoxy)phenyl][[3-(1,1,2,2-tetrafluoroethoxy)phenyl]-methyl]amino]-1,1,1-trifluoro-2-propanol (33.8 mg, 0.06 mmol) in ethanol and 5% palladium on carbon (4 mL) was placed under 40 psi hydrogen gas for 7 h. The mixture was filtered through celite, the solvent was evaporated, and the residue was purified by silica gel chromatography eluting with 25% ethyl acetate in hexane to give 13.4 mg (42%) of (EX-450A) as 3-[[3-(4-aminophenoxy)phenyl][[3-(1,1,2,2-tetrafluoroethoxy)phenyl]methyl]amino]-1,1,1-trifluoro-2-propanol and 13.9 mg (41%) of (EX-450B) as 3-[[3-[4-(ethylamino)phenoxy]phenyl][[3-(1,1,2,2-tetrafluoroethoxy)phenyl]methyl]amino]-1,1,1-trifluoro-2-propanol both as orange oils. 3-[[3-(4-aminophenoxy)phenyl] [[3-(1,1,2,2-tetrafluoroethoxy)phenyl]methyl]-amino]-1,1,1-trifluoro-2-propanol: HRMS calcd. for C24H22F7N2O3: 519.1519 [M+H]+, found: 519.1529. 1H NMR (acetone-d6) δ 3.63 (dd, 1H), 3.96 (dd, 1H), 4.42-4.58 (m, 1H), 4.80 (s, 2H), 5.88 (m, 1H), 6.20 (m, 1H), 6.32-6.77 (m, 6H), 6.92 (d, 1H), 7.06-7.26 (m, 3H), 7.43 (m, 1H). 3-[[3-[4-(ethylamino)phenoxy]phenyl][[3-(1,1,2,2-tetrafluoroethoxy)phenyl]-methyl]amino]-1,1,1-trifluoro-2-propanol: HRMS calcd. for C26H26F7N2O3: 547.1832 [M+H]+, found: 547.1819. 1H NMR (acetone-d6) δ 1.23 (t, 3H), 3.17 (q, 2H), 3.63 (dd, 1H), 3.96 (dd, 1H), 4.42-4.58 (m, 1H), 4.79 (s, 2H), 5.85 (d, 1H), 6.20 (m, 1H), 6.33 (m, 1H), 6.47 (m, 1H), 6.50 (tt, 1J), 6.61 (d, 2H), 6.78 (d, 2H), 7.09 (t, 1H), 7.20 (m, 1H), 7.23 (d, 1H), 7.42 (m, 1H).
