Process for the production of 2-chloro-5-chloromethyl-pyridine |
| abstract |
A process for the production of 2-chloro-5-chloromethylpyridine of the formula: ##STR1## starting from 6-hydroxynicotinic acid of the formula: ##STR2## In this way 6-hydroxynicotinic acid is reacted with an acid chloride to 6-hydroxynicotinoyl chloride of the formula: ##STR3## The latter is then catalytically hydrogenated with hydrogen to 6-hydroxy-5-hydroxymethylpyridine of the formula: ##STR4## The latter is then catalytically hydrogenated with hydrogen to 2-hydroxy-5-hydroxymethylpyridine of the formula: ##STR5## which is then chlorinated to the end product according to formula I. |
