PROBLEM TO BE SOLVED: To provide a method for producing the subject high-quality compound by using an N-arylsulfonyl-N'-alkylurea as the reaction product from the aimed aromatic sulfonyl isocyanate and an aliphatic amine readily available as an alternative to aliphatic isocyanate catalysts not standing on the market. SOLUTION: This compound, an aromatic sulfonyl isocyanate of the general formula [III]: R<1> SO2 NCO (R<1> is phenyl or naphthyl group which is optionally substituted by an alkyl group, a halogen atom or nitro group), is obtained by reaction between an aromatic sulfonamide of the general formula [I]: R<1> SO2 NH2 (R<1> represents the same meaning as described above) and phosgene by the use of an urea compound of the general formula [II]: R<1> SO2 NHCONHR<2> (R<1> represents the same meaning as described above; R<2> is a 3-8C alkyl or cycloalkyl group). |
