115010-11-2, 2,3-Dihydro-1-benzofuran-5-sulfonoylchloride is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
EXAMPLE 1; N-[7-(4-piperidinyl)oxy-1-benzofuran-5-yl]-2-methoxy-5-methylbenzenesulfonamide; Example 1 was prepared as follows: 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. Hydrolysis of 7-iodo-N-(2-methoxy-5-methylphenyl)-1-benzofuran-5-sulfonamide in alkaline solution using copper as catalyst results in 7-hydroxy-N-(2-methoxy-5-methylphenyl)-1-benzofuran-5-sulfonamide. Reaction with a methyl carbamate protected mesylate of 4-hydroxypiperidine, results in methyl 4-[(5-{[(2-methoxy-5-methylphenyl)amino]sulfonyl}-1-benzofuran-7-yl)oxy]piperidine-1-carboxylate, which is hydrolysed in alkaline solution giving the title compound.
115010-11-2, As the paragraph descriping shows that 115010-11-2 is playing an increasingly important role.
