HCID 68469651[2-(5,6-dimethoxy-1-methyl-1H-pyrrolo[3,2-b]pyridin-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-4-ylmethyl]-[2-(3-methyl-3H-imidazol-4-yl)ethyl]amineYield 95.4%

Procedure

The product is prepared by following the procedure described in example 34 stage (j) starting with 0.06 g of 2-(5,6-dimethoxy-1-methyl-1H-pyrrolo[3,2-b]pyridin-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-4-carbaldehyde and 0.05 g of 3-methylhistamine dihydrochloride instead of the cyclopropylamine used in example 34 stage (j). After purification by flash-pack chromatography (SiO2, dichloromethane/methanol 98/02 by volume as eluents), 0.070 g of [2-(5,6-dimethoxy-1-methyl-1H-pyrrolo[3,2-b]pyridin-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-4-ylmethyl]-[2-(3-methyl-3H-imidazol-4-yl)-ethyl]amine is obtained with the following characteristics:
