| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| Application | 2, 6-pyridine dicarbonyl chloride is an organic intermediate and pharmaceutical intermediate that can be used in acylation reactions. It is mainly used in laboratory research and development. In the process of chemical and pharmaceutical research and development, it can be prepared from 2, 6-pyridinedicarboxylic acid and oxalyl chloride. |
| preparation | report 1. dissolving 2,6-pyridinedicarboxylic acid (5.00g,30mmol) as raw material in dichloromethane, adding oxalyl chloride (11.43g,90mmol) dropwise at 0 ℃, heating the solution to 25 ℃ after the dropwise addition, stirring the reaction to produce 2,6-pyridinedicarboxylic chloride in a yield of 95%; it is reported that the 2. dissolves 2, 6-pyridinedicarboxylic acid in dichloromethane, then adds a certain amount of dichlorosulfoxide, and refluxes at 70°C to remove the pyridine -2, 6-dicarboxylic acid Two carboxyl acyl chlorides are chlorinated, and finally the impurities produced are removed to prepare 2, 6-pyridine dicarbonyl chloride. |
