3,5-Dimethylaniline was synthesized from 2,4-dimethylaniline.The reaction steps of acylation,nitration,hydrolysis/deacetylation,diazotization/deamination and reduction were improved.Acylation and nitration,hydrolysis/deacetylation and diazotization/deamination were combined respectively.The total synthesis steps were decreased from five to three by the one-vessel reactions.The product 3,5-dimethylaniline with an overall yield of 75% and a purity of 98.9% was obtained.
