0.094 cm3 of 4-(trifluoromethoxy)phenyl isocyanate is added to a solution of 0.080 g of (2,4-dimethoxybenzyl)[2-(5,6-dimethoxy-1-methyl-1H-indol-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyrid-4-ylmethyl]amine in 6 cm3 of dichloromethane, under an argon atmosphere, at a temperature in the region of 20° C. The reaction medium is stirred at this same temperature for 24 hours. 2 cm3 of water are added. After separation of the phases by settling, the organic phase is dried over magnesium sulfate, filtered and then concentrated under reduced pressure. After purification by flash-pack chromatography (SiO2, dichloromethane/methanol 98/02 by volume as eluent), 0.150 g of 1-(2,4-dimethoxybenzyl)-1-[2-(5,6-dimethoxy-1-methyl-1H-indol-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyrid-4-ylmethyl]-3-(4-trifluoromethoxyphenyl)urea is obtained, the characteristics of which are as follows:
