Summary The principle of the synthesis of 3-halomethyl-2, 6-dichloro-pyridines has been extended to compounds with side chains of more than one carbon atom in the 3-position. Feasible synthetic routes are outlined starting from cheap, commercially available a- methylideneglutaronitrile and trichloroalkyl functional compounds which yield the intermediate 1, 3, 5-trisubstituted alkanes. These are cyclized by aqueous mineral acid or ...
