Procedure

To a THF (4 mL) solution of 3[(3-phenoxyphenyl)[[3-bromophenyl]methyl]amino]-1,1,1-trifluoro-2-propanol (0.60 g, 1.3 mmol) from EX-595B was added benzyl-magnesium bromide in THF (2.0 mL, 2.0 M, 4.0 mmol) and Pd(PPh3)4. The resulting yellow solution was refluxed under N2 for 18 h. The cooled solution was poured into saturated aq. NH4Cl, extracted with ethyl acetate, dried (MgSO4) and evaporated to an oil. Purification by flash chromatography on silica gel eluting with 15% ethyl acetate in hexane gave an oil which was dissolved in EtOH, stripped and dried in vacuo to give 0.39 g (62%) of the desired 3[(3-phenoxyphenyl)[[(3(phenylmethyl)phenyl]methyl]amino]-1,1,1-trifluoro-2-propanol product as a colorless oil.
