| titleOfInvention | Synthesis method of 2-acetamido-5-bromopyridine |
| abstract | The invention relates to a synthesis method of 2-acetamido-5-bromopyridine. 2-amino-5-bromopyridine and acetic anhydride are used as raw materials; the mol ratio of the 2-amino-5-bromopyridine to the acetic anhydride is 1: (0.85 to 3.6); in a proper solvent, the continuous reaction is performed at 45 to 115 DEG C to generate a coarse product of 2-acetamido-5-bromopyridine; after the purification, a pure product of the 2-acetamido-5-bromopyridine is obtained. The method has the advantages that the raw materials can be easily obtained; the price is reasonable; meanwhile, heavy metal and corrosive gas are not used in the preparation reaction; the reaction is mild; no special requirements exist on reaction equipment; the production can be performed by ordinary anti-corrosion equipment; in addition, the reaction conditions of the method are proper; no pollution can be caused on the environment. |
