Procedure

To a solution of 3-[(3-phenoxyphenyl)[[3-(1,1,2,2-tetrafluoroethoxy) phenyl]-methyl]amino]-1,1,1-trifluoro-2-propanol (474 mg, 0.00094 mol) in 4.5 mL of dichloromethane at 0° C. was added (diethylamino)sulfur trifluoride (378 mg, 0.0023 mol). The reaction mixture was warmed to room temperature and stirred for 2 h, then quenched with water and extracted with dichloromethane. The organic layers were combined, dried over MgSO4, and concentrated in vacuio. The crude product was purified by column chromatography on silica gel eluting with 1:9 ethyl acetate in hexane to afford 240 mg (50%) of the desired N-(3-phenoxyphenyl)-N-(3,3,3,2-tetra-fluoropropyl)-3-(1,1,2,2-tetrafluoroethoxy)benzenemethanamine product as a yellow oil. HRMS calcd. for C24H19F8NO2: 506.1366 [M+H]+, found: 506.1368. 1H NMR (CDCl3) 67 7.26 (m, 3H), 7.20 (m, 5H), 6.87 (d, 2H), 6.62 (d, 1H), 6.50 (s, 1H), 6.49 (d, 1H), 5.87 (t, 1H), 4-89 (d, 1H), 4.77-4.52 (m, 1H), 4.73 (d, 1H), 4.60 (s, 2H). 19F NMR (CDCl3) δ −69.83 (t, 3F), −88.63 (s, 2F), −137.19 (dt, 2F), −228.82 (1F).
