Versuchsvorschrift

To a solution of 3-iodo-4-methoxy-1H-pyrrolo[3,2-c]pyridine (200 mg) in DMF (6 ml) were added 15-crown-5 (0.159 ml) and sodium hydride (60% dispersion in mineral oil, 32.1 mg), and the mixture was stirred at room temperature for 1 hr. To the reaction mixture was added 1,2,3-trifluoro-5-nitrobenzene (0.101 ml), and the mixture was stirred overnight at room temperature under nitrogen atmosphere. The reaction mixture was extracted with water and ethyl acetate, and the organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (258 mg).
