Reaction Steps
A solution of 2-[6-(2-chloroethoxy)-5-methoxy-1-methyl-1H-indol-3-yl]-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.660 g, 1,294 μmol) in methyl ethyl ketone (10 ml) is placed in a 50 ml single-necked flask and sodium iodide (0.29 g; 1.941 mmol) is then added. The reaction mixture is refluxed for 16 hours. Analysis by thin layer chromatography (50/50 cyclohexane/ethyl acetate) shows that the reaction has come to an end. After returning to 20° C., the reaction mixture is evaporated under reduced pressure and the residue is taken up in a mixture of water (50 ml) and dichloromethane (50 ml), which is separated by settling out; the organic extract is washed with water (30 ml) and dried over magnesium sulfate. After evaporation, the compound obtained is purified by chromatography on silica gel (cartridge FC-10-Si-BP-Sup, 10 g of silica with a particle size of 15-35 μm, elution being carried out with a 70/30 mixture of cyclohexane/ethyl acetate). The fractions containing the expected: compound are combined and then evaporated under reduced pressure, giving 2-[6-(2-iodoethoxy)-5-methoxy-1-methyl-1H-indol-3-yl]-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.695 g; 89%) the characteristics of which are as follows:
