The title compound was prepared by one-pot reductive alkylation of the chiral amine (III) with 3-(2-chlorophenyl)propionitrile (XI). Reduction of nitrile (XI) by means of DIBAL at -78 C produced the intermediate diisobutylaluminium-imine complex (XII) which, after addition of (R)-3-methoxy-alpha-methylbenzylamine (III), generated imine (XIII). Subsequent reduction of imine (XIII) with NaBH4 afforded the target amine.
