実験手順

To a homogeneous mixture of (4-fluorophenyl)methanamine (2.5 mL, 21.8 mmol) and 4′-chlorobiphenyl-3-carbaldehyde (Aldrich, 3.6 g, 16.8 mmol) in anhydrous dichloroethane (25 mL), under nitrogen atmosphere, was added acetic acid (1.2 mL, 21.0 mmol). The mixture was stirred at room temperature for 13.5 h before sodium triacetoxyborohydride (5.0 g, 23.5 mmol) was added. After 4 h, (4-fluorophenyl)methanamine (2.5 mL, 21.8 mmol) was added and the stirring continued. After an additional 5 h of stirring, the reaction was quenched with 1 N aq. NaOH solution (50 mL) then extracted twice with chloroform. The organic extracts were combined, washed with saturated aqueous NaHCO3 and brine, dried over anhydrous MgSO4, filtered and concentrated in vacuo. The residue was purified by silica gel flash chromatography (Merck KGaA, 230-400 mesh particle size) eluting with 0-70% ethyl acetate in hexane, to afford the title compound (3.43 g, 59%) as a colorless oil. MS (ESI): 326.1 (M+H)+.
