Procedure

To a solution of 1-fluoro-3-(1-(4-fluorophenyl)-1-isocyano-2-phenylethyl)-5-(trifluoromethyl)benzene (20 mg, 0.052 mmol) in MeOH (0.4 mL) was added 4 N HCl in dioxane (0.3 mL) and the reaction mixture was stirred for 3 minutes. The reaction solvent was evaporated under a stream of nitrogen. The residue was diluted with 1 N NaOH (5 mL) and the aqueous portion was extracted with Et2O (3×5 mL). The combined organic fractions were washed with sat. NaCl (5 mL), dried over Na2SO4, filtered and evaporated under vacuum to yield 1-(3-fluoro-5-(trifluoromethyl)phenyl)-1-(4-fluorophenyl)-2-phenylethanamine (19 mg, 97% yield) as a clear glass.
