To prepare 1% 2C4-phenylenediamine, N4- [ (4-fluorophenyl) methyl] -2-nitro, the method is as follows:
First take an appropriate amount of 4-fluorobenzyl chloride, place it in a clean reactor, use alcohol as a solvent, often ethanol is preferred, and add potassium carbonate to the kettle, which is an acid binding agent, which can promote the reaction. Slowly heat up to a suitable temperature, about 60 to 70 degrees Celsius, maintain this temperature, and stir well. Then slowly add 2-nitro-1% 2C4-phenylenediamine to the kettle, add it, and continue to stir for a number of reactions, about 4 to 6 hours. At this time, 4-fluorobenzyl chloride and 2-nitro-1% 2C4-phenylenediamine undergo a nucleophilic substitution reaction to form the prototype of the desired product.
After the reaction is completed, the reaction solution is cooled to room temperature, diluted with water, and then extracted with an organic solvent. Dichloromethane is commonly used. After multiple extractions, the product is enriched in the organic phase. After extraction, the organic phase is dried with anhydrous sodium sulfate to remove the moisture. Then, the organic solvent is removed by vacuum distillation to obtain a crude product.
To obtain a pure product, the crude product needs to be refined. Column chromatography is often used, with silica gel as the stationary phase, and the mixed liquid of petroleum ether and ethyl acetate in an appropriate proportion as the mobile phase for separation. The fractions containing the target product are collected and distilled under reduced pressure again to remove the mobile phase, and the final product is pure 1% 2C4-phenylenediamine, N4- [ (4-fluorophenyl) methyl] -2-nitro. The whole process should pay attention to the reaction temperature, material ratio and operation standards to ensure the purity and yield of the product.
