| titleOfInvention | A kind of preparation method of N-cyclopropylmethylaniline compound |
| abstract | The present invention relates to a preparation method of N-cyclopropylmethylaniline compounds. The preparation method comprises the following steps: using a compound represented by formula II and cyclopropylcarbaldehyde as raw materials, hydrogenation is carried out under the action of an acid and a catalyst The reaction is carried out to obtain the N-cyclopropylmethylaniline compound shown in formula I, wherein R is selected from alkoxy group, alkylamino group or substituted aniline group shown in formula III. The preparation method involved in the present invention utilizes the compound of formula II and cyclopropyl formaldehyde as raw materials, and through the method of catalytic hydrogenation, the two-step reaction of nitro reduction and amino alkylation is carried out by a "one-pot method", which reduces the post-processing operation. , the process is simple, the operation is simple, the cost is low, the production is clean, the yield of the reaction is improved, and the method is suitable for industrial production. The preparation method produces less impurities, so that the yield of the product is high, and the product can be obtained with high purity by simple post-processing without complicated and lengthy post-processing. |
