The present invention relates to the preparation of 5-aminomethyl-2-chloropyridines by reacting a mixture of 5-chloromethyl-2-chloropyridine and 5-dichloromethyl-2-chloropyridine with substituted amines. The mixture of 5-chloromethyl-2-chloropyridine and 5-dichloromethyl-2-chloropyridine is obtained by chlorination of 5-methyl-2-chloropyridine.
