Sodium borohydride → 5-{[1-(3,4-Difluorophenyl)ethylamino]-(4-methoxyphenyl)methyl}-2,3-dimethoxyphenylamine

Participants

Reaction Steps

Following a reaction and purification procedure similar to those described in Example (1b), 950 mg of N-[1-(3,4-difluorophenyl)ethyl]-N-[(3,4-dimethoxy-5-nitrophenyl)-(4-methoxyphenyl)methyl]amine [prepared as described in step (a) above], 985 mg of nickel chloride hexahydrate and 330 mg of sodium borohydride were reacted. The crude product was purified by chromatography through a silica gel column using a 10:1 by volume mixture of toluene and ethyl acetate as eluant, to afford isomer A of the title compound (215 mg) as a yellow oil and isomer B of the title compound (370 mg) as a yellow oil, respectively.
