Using Pt/C as a catalyst, the hydrogenation and Bamberger rearrangement of o-nitrotoluene was carried out in a solution consisting of methanol, sulfuric acid and acetic acid, to afford 2-methyl-4-meth- oxyaniline. The intermediate product was further reacted with cyclohexanone in the presence of Pd/C in phenol to form N-phenyl-2-methyl-4-methoxyaniline. The total yield is 63%. The product as well as intermediate was determined by 1H NMR and MS spectra. The factors of affecting the reactions were also discussed.

Key words: synthesis, Bamberger rearrangement, N-phenyl 2-methyl-4-methoxyaniline, o-nitrotoluene
