Procedimiento

The 2-cyano-3-chloromethylpyridine was prepared by chlorination of 2-cyano-3-methylpyridine in chlorobenzene with benzoylperoxide by gradual addition of SO2Cl2 at 80° C. 2-Cyano-3-chloromethylpyridine was obtained in 60-65% conversion. The main impurities are 2-cyano-3-dichloromethylpyridine and unreacted 2-cyano-3-methylpyridine, which do not cause problems in the process of this Preparation.
