<p>PURPOSE:To obtain the titled compound useful as a raw material for herbicides, insecticides and photographic couplers in high yield, by chlorinating at least one hydrogen atom of the phenyl nucleus of a beta-imidated chlorophenylhydrazine based compound. CONSTITUTION:A beta-imidated phenylhydrazine based compound is dissolved in a solvent, e.g. chloroform or benzene, and chlorine atom is introduced into the phenyl group with a chlorinating agent, e.g. chlorine gas or sulfuryl chloride. The resultant beta-imidated chlorophenylhydrazine based compound can be used as a useful intermediate for herbicides or photographic couplers, etc., and starting material for chlorophenylhydrazine without separating from the reaction system.</p> |
