According to a quick Reaxys search, this transformation has been published by Cai J. et al. in Bioorganic and Medicinal Chemistry, 2015 , vol. 23, # 4 p. 657 - 667 over 4 steps (see Link)

1) Protection of NH2 with Acetylgroup

2) ortho-Nitration of A

3) deprotection of Acetylgroup

4) reduction of nitrogroup to aminogroup to yield 4-methylbenzene-1,2-diamine

dear Dr.Michael Päch

than you very much,I am sorry to write this sentence"give me suitable method"

Acetylation, Nitration,Deprotection of acetylated product and finally reduction of nitro to amine I.e required product

thanks a lot Lukas Holz

please if you can send that paper,because i tried searched in google but failed

I don't think there is any other simpler scheme for the preparation from p-toluidine.

First carry out acetylation of p-toluidine(Protection), then nitration followed by hydrolysis  it mono  amino , nitro product  which you can  reduced by Fe in HCl  to get desired product.

thank you very much for every one

Dear ones,

you can also synthesis  from o-nitro para methyl chlorobenzene using

1. Ar-SN2 on o-nitro para methyl chlorobenzene gives o-nitro para methyl aniline using NH3,.

2. Reduction of o-nitro para methyl aniline using Fe in HCl  to get your final product

Why bother.. it is commercially available.. try ApolloChemicals

how to synthesis of 4-chloro-5-methylbenzene-1,2-diamine
