| Abstract: | 3-Amino-4-methoxy-acetanilide, an important intermediate for disperse azo dyes, was prepared by selective acylation of 2,4-diaminoanisole, which was synthesized by hydrogenation of 2,4-dinitroanisole in the presence of Raney Ni. 2,4-Dinitroanisole was produced from 2,4-dinitrochlorobenzene. The total yield was over than 80%. |
