Procedure

EX-435A) A solution of ethyl 3-[[3-[[[3-(1,1,2,2-tetrafluoroethoxy) phenyl]methyl]-(3,3,3-trifluoro-2-hydroxypropyl)amino]phenoxy]methyl]benzoate (22.1 mg, 0.04 mmol) and lithium hydroxide (5 mg, 0.12 mmol) in water (1 mL) and tetrahydrofuran (0.5 mL) was heated at 80° C. for 16 h. The reaction mixture was added to 6 N hydrochloric acid and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, and the solvent was evaporated. The residue was purified by reverse phase HPLC eluting with 10% to 90% acetonitrile in water to afford 5.6 mg (19%) of the desired benzoic acid product as a brown oil. HRMS calcd. for C26H23F7NO5: 562.1464 [M+H]+, found: 562.1418. 1H NMR (acetone-d6) δ3.64 (dd, 1H), 3.95 (m, 1H), 4.45-4.50 (m, 1H), 4.80 (s, 2H), 5.12 (s, 2H), 6.27-6.63 (m, 4H), 7.06-7.27 (m, 4H), 7.41 (t, 1H), 7.50 (t, 1H), 7.66 (d, 1H), 7.99 (d, 1H), 8.10 (s, 1H).
