In a 100 ml round-bottomed flask, a mixture of 69 mg of 5-(3H-imidazo[4,5-c]pyridin-2-yl)-9H-pyrrolo[1,2-a]indol-9-ylamine obtained according to stage 4 of Example 3, 48 mg of 6-chloro-1H-pyrrolo[2,3-b]pyridine-4-carboxylic acid obtained according to the preceding stage, 51 mg of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDCI) and 36 mg of 1-hydroxybenzotriazole (HOBt) in 5 ml of dimethylformamide is stirred for 3 hours under argon at ambient temperature. The reaction medium is evaporated to dryness under vacuum and the residue is chromatographed on silica gel (15-40 μm), elution being carried out with a gradient of methanol (4% to 6% v/v) in dichloromethane. The valuable fractions are combined and evaporated to dryness under vacuum, the residue is triturated from a solution of sodium bicarbonate and filtered, and the solid is washed with water. The precipitate is dissolved in methanol and the solvent is evaporated to dryness under vacuum. 11 mg of 6-chloro-1H-pyrrolo[2,3-b]pyridine-4-carboxylic acid [5-(3H-imidazo[4,5-c]pyridin-2-yl)-9H-pyrrolo[1,2-a]indol-9-yl]amide are obtained in the form of a solid, the characteristics of which are the following:
