p-Toluenesulfonic acid → thiophene-2-sulfonic acid [2-(5,6-dimethoxy-1-methyl-1H-indol-3-yl)-1H-pyrrolo[2,3-b]pyrid-4-ylmethyl]amide

Participants

Reaction Steps

Thiophene-2-sulfonic acid [2-(5,6-dimethoxy-1-methyl-1H-indol-3-yl)-1H-pyrrolo[2,3-b]pyrid-4-ylmethyl]amide is prepared as described in Example 210 starting with 0.1 g of thiophene-2-sulfonic acid (2,4-dimethoxybenzyl)[2-(5,6-dimethoxy-1-methyl-1H-indol-3-yl)-1H-pyrrolo[2,3-b]pyrid-4-ylmethyl]amide instead of the N-(2,4-dimethoxybenzyl)-N-[2-(5,6-dimethoxy-1-methyl-1H-indol-3-yl)-1H-pyrrolo[2,3-b]pyrid-4-ylmethyl]-4-trifluoromethoxybenzenesulfonamide used in Example 210 and 0.110 g of para-toluenesulfonic acid. 0.025 g of thiophene-2-sulfonic acid [2-(5,6-dimethoxy-1-methyl-1H-indol-3-yl)-1H-pyrrolo[2,3-b]pyrid-4-ylmethyl]amide is obtained, the characteristics of which are as follows:
