Preparation of N-Methyl-4-nitroaniline: it is prepared by reaction of acetanilide of nitrate,  iodomethane and ethanol. Firstly, acetone, nitro acetanilide and potassium hydroxide are mixed and refluxed. Meanwhile, dropping methyl iodide acetone solution and refluxing for another 4 hours. After reactant is placed overnight, crystal precipitated is washed with ethanol to get N-methyl-nitro acetanilide. Secondly, the reactant is mixed with ethanol, hydrochloric acid, and refluxed for 8 hours. Crude product is generated by washed and drying. At last, product is obtained by dissolution, filtration and precipitation of crystals.

Uses of N-Methyl-4-nitroaniline: it is used to produce N-methyl-4-nitro-N-nitroso-aniline. The reaction occurs with reagents NO, O₂ and solvent 1,2-dichloro-ethane with ambient temperature for 24 hours. The yield is about 90%.
