Preparation method of 3-amino-4-methoxybenzaniline
The invention relates to a preparation method of 3-amino-4-methoxybenzaniline.The preparation method includes the steps that 3-nitro-4-X-benzoic acid reacts with aniline under a reaction agent condition to obtain 3-nitro-4-X-benzanilide; 2, 3-nitro-4-X-benzanilide reacts with methyl alcohol under the presence of alkaline reagent to obtain 3-nitro-4 methoxybenzaniline; reduction reaction is performed with treatment or without treatment, so that 3-amino-4-methoxybenzaniline is obtained.The method is high in product yield, low in cost, good in quality and convenient to industrialize and meets the requirement for environmentally-friendly production.
