Procedure

To a 1,2-dichloroethane (4 mL) solution of the aldehyde (0.19 g, 1.1 mmol) from EX-608D was added 3-phenoxyaniline (0.20 g, 1.1 mmol), NaB(OAc)3H (0.30 g, 1.4 mmol) and acetic acid (0.065 mL, 1.1 mmol). The cloudy solution was stirred at room temperature for 3 h. The reaction mixture was poured into water and extracted with dichloromethane. The organic layer was washed with saturated NaHCO3 and brine, dried (MgSO4) and evaporated to yield 0.32 g (84%) of the desired N-(3-phenoxyphenyl)-[[3-(tetrahydro-2-furanyl)phenyl]methyl]amine product as a yellow oil which was used without further purification. The formation of the desired product was monitored by TLC.
