Participants

Reaction Steps

Following a similar reaction, separation and purification procedure to that described in Example (59b), 18.44 g of N-[(R)-1-(3,4-difluorophenyl)ethyl]-N-[(4-fluorophenyl)-(3-nitrophenyl)methyl]amine, 22.69 g of nickel chloride hexahydrate, 7.22 g of sodium borohydride and 150 ml of methanol were reacted, to obtain 1.27 g of isomer A and 2.79 g of isomer B of the title compound, respectively, each as a pale yellow oil.
