Abstract

Described herein are novel methods of synthesizing (3-chloro-2-pyridyl)hydrazine. Compounds prepared by the methods disclosed herein are useful for preparation of certain anthranilamide compounds that are of interest as insecticides, such as, for example, the insecticides chlorantraniliprole and cyantraniliprole.
