Versuchsvorschrift

7-iodo-N-(2-methoxy-5-methylphenyl)-1-benzofuran-5-sulfonamide is produced starting from 2,3-dihydrobensofuran. Treatment with chlorosulfonic acid gives the corresponding sulfonyl chloride, which is iodinated using iodine monochloride. Aromatization is done using NBS, resulting in 7-iodo-N-(2-methoxy-5-methylphenyl)-1-benzofuran-5-sulfonamide after treatment with cresidine.
