Reaction Steps

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.
