The intermediate chiral diamine (IV) (see Scheme no. 28794701a, intermediate (V)) is prepared as follows: Reduction of N-Boc-D-alanine methyl ester (I) with DIBAL affords N-Boc-alaninal (II), which is reductively aminated with dimethylamine in the presence of NaBH3CN to afford the Boc-protected diamine (III). The N-Boc group of (III) is finally removed under acidic conditions to provide the target (R)-diamine (IV).
