The intermediate phenylenediamine (VI) was prepared as follows. Reaction of 5-chloro-2-nitroaniline (I) with sodium methoxide afforded 5-methoxy-2-nitroaniline (II), which was subsequently converted to the N-Boc derivative (III). Methylation of (III) with iodomethane and NaH, followed by acidic treatment of the resulting N-methyl carbamate (IV), produced the N-methyl aniline (V). The nitro group of (V) was then reduced with the combination SnCl2-NaBH4 to furnish the diamine (VI).
