Procedure

The title compound was prepared by the same procedure for preparing (6,4′-dimethoxy-biphenyl-3-ylmethyl)-(1-pyridin-3-yl-ethyl)-amine from 1-Pyridin-4-yl-ethylamine (245 mg, 2 mmol), 6,4′-Dimethoxy-biphenyl-3-carbaldehyde (121 mg, 0.5 mmol) and sodium triacetoxyborohydride (212 mg, 1.0 mmol, Aldrich). The title compound was purified by column chromatography (silica gel, ethyl acetate) in form as white solid in 51% yield (89 mg, 0.26 mmol).
