| titleOfInvention | Preparation method of 2-chloro-3-aminopyridine |
| abstract | The invention discloses a new preparation method of 2-chloro-3-aminopyridine. The method comprises the following steps of: using 2-pyridone as the raw material to perform a nitration reaction and an N-alkylation reaction for amino protection to obtain N-alkyl-3-nitro-2-pyridone, then adding a proper chlorinating agent to perform a directional chlorination reaction and a dealkylation protection reaction to obtain 2-chloro-3-nitropyridine, and finally reducing to obtain 2-chloro-3-aminopyridine. The method has cheap and available raw materials, high selectivity, fewer by-products and high yield. |
