The object of the present invention is to provide a novel method for producing an isothiocyanate compound having a carboxyl group(s) by a reaction of the corresponding amino compound having a carboxyl group(s), thiocarbonyldiimidazole and a base, in one step with high purity. An amino compound having a carboxyl group(s) is reacted with thiocarbonyldiimidazole in a solvent in the presence of a base to obtain an isothiocyanate compound having a carboxyl group(s).
