Directed ortho lithiation of 2-methoxypyridine (1) has been regioselectively achieved at position 3 by using methyllithium catalyzed by a small amount of diisopropylamine.This metalation methodology, called "catalyzed metalation", gave good results whereas other metalation routes failed.This allowed the convenient synthesis of various 3-substituted 2-methoxypyridines of general interest.
