The 3-(2,2,2-trifluoroethoxy)benzaldehyde (0.360 g, 1.76 mmol) product from EX-659A and 3-phenoxyaniline (0.326 g, 1.76 mmol) were combined in 50 mL of cyclohexane with 3 Å molecular sieves (1 g) and stirred overnight at 80° C. The mixture was cooled, filtered, and evaporated, then dissolved in 50 mL of methanol and cooled to 0° C. Solid sodium borohydride (0.030 g, 0.79 mmol) was added in portions, and the mixture was stirred overnight. The reaction was quenched with 5% aq. NaHCO3 and extracted with ether (3×). The combined ether layers were washed with water and brine, dried over MgSO4, filtered, and evaporated to give 0.50 g (76%) of the desired N-(3-phenoxyphenyl)[[3-(2,2,2-trifluoroethoxy)phenyl]methyl]amine product as an amber oil, >95% pure by normal phase HPLC analysis. MS m/z=373 [M+].
