Method for producing colorless esters of pyridine carboxylic acids |
| abstract |
COLORLESS ESTERS OF PYRIDINE CARBOXYLIC ACID ARE OBTAINED BY THE REACTION OF AN ALCOHOL WITH THE PYRIDINE CARBOXYLIC ACID CHLORIDE. THE ACID CHLORIDE IS PREPARED BY THE REACTION OF THE FREE ACID WITH PHOSPHOURS OXYCHLORIDE IN SOLUTION IN A TERTIARY AMINE, SUCH AS PYRIDINE, AND THE ESTERIFICATION EFFECTED BY ADDITION OF ALCOHOL TO THE REACTION MIXTURE. THE ESTER IS PRECIPITATED BY THE ADDITION OF WATER. |
