Procedure

To a solution of 2-(1-indenyl)benzaldehyde (7.0 mmol) in ethanol (19.4 mL) was added dropwise aniline (7.3 mmol) under a nitrogen atmosphere. The mixture was stirred at room temperature. After disappearance of the aldehyde was confirmed by gas chromatography, The solvent was distilled off under reduced pressure. After addition of ethanol (19.4 mL), sodium borohydride (4.5 mmol) was added to the solution and the mixture was reacted at room temperature for 3 hrs. Water and toluene were then added to the reaction mixture. The organic layer was dried and concentrated. The obtained oily substance was purified by silica gel column chromatography to give N-[2-(1-indenyl)phenylmethyl]-N-phenylamine (1.48 g, yield 24.0%) as a yellow oily substance.
