| titleOfInvention | Process for the preparation of chloromethylpyridines |
| abstract | The present invention is characterized by reacting a pyridine derivative of formula (II) with a formamide derivative of formula (III) and a chlorinating agent, optionally in the presence of a diluent, at a temperature of 20 to 120 ° C. A novel process for preparing chloromethylpyridine of formula (I).n n n n n n n n In the above formulan n n X 1 is hydrogen, halogen or alkyl,n n n R 1 is hydrogen, alkyl or optionally substituted phenyl,n n n R 2 and R 3 are the same or different and are alkyl or cycloalkyl or together represent alkanediyl. The present invention also relates to novel pyridine derivatives of formula (II) and methods for their preparation. |
