| titleOfInvention | Preparation method of 2-aminopyridine-4-methyl alcohol |
| abstract | The invention discloses a preparation method of 2-aminopyridine-4-methyl alcohol, which comprises the following steps: 2-chloropyridine-4-carboxylic acid is used as a raw material to be in esterification reaction with micromolecule alcohol so as to obtain 2-chloropyridine-4-carboxylic acid ester under the function of sulfoxide chloride; 2-chloropyridine-4-carboxylic acid ester is reduced to 2-chloropyridine-4-methyl alcohol under the function of a reducing agent; finally, 2-chloropyridine-4-methyl alcohol and ammonia water are in ammonolysis reaction so as to obtain 2-aminopyridine-4-methyl alcohol under the catalysis of a copper catalyst. With adoption of the preparation method, the process route is short, generation of large amount of waste liquid and waste residue is avoided, and pollution to the environment is reduced; in addition, the product yield is high, the copper-class catalyst in the ammonolysis reaction can be recycled, the production cost is reduced, and the preparation method is suitable for industrial production. |
