摘要： A method of preparing certain 2-halo-5-methylpyridines, useful as herbicide intermediates, is presented starting from acyclic pentenes. The pentene is difunctionalized, e.g., by making the epoxide, and is then reacted with a nitrogen source to close the ring. The nitrogen-containing 6-membered heterocycle may then be aromatized readily to produce the 2-halo-5-methylpyridine desired. Also part of the invention are novel acyclic and cyclic intermediates used in the process.
