IMINO CHLORIDE DERIVATIVE PRODUCTION METHOD AND PHENYLIMIDAZOLE DERIVATIVE PRODUCTION METHOD

PROBLEM TO BE SOLVED: To provide an imino chloride derivative production method and a phenylimidazole derivative production method which are highly safe and can achieve a high yield.SOLUTION: A compound represented by the general formula (1) and a chlorinating agent are reacted in the presence of a nitrogen-containing reaction aid, to produce an imino chloride derivative represented by the general formula (2). [In the formulas, Rand Rrepresent a branched alkyl group having three or more carbon atoms or a cycloalkyl group; Rrepresents a substituent; Rrepresents an aromatic hydrocarbon ring group or an aromatic heterocyclic group; and n represents an integer between 0 and 3.]
