Reaction Steps

4-Chloro-1H-pyrrolo[3,2-c]pyridine (247 mg) synthesized by the method disclosed in WO2007/095223 was dissolved in DMF (7.0 ml). After cooling to 0° C., N-iodosuccinimide (382 mg) was added thereto. The resulting mixture was stirred at room temperature for 1 hour, and then chloroform and water were added thereto to separate the organic layer. After the organic layer was dried over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure. The resulting residue was purified by silica gel column chromatography (developing solvent: hexane/ethyl acetate) to obtain the title compound as a dark-brown solid (455 mg). Physical properties: m/z [M+H]+ 279.1
