Reaction Steps

5-(2-Fluorophenyl)-4-iodo-1-(pyridin-3-ylsulfonyl)-1H-pyrrole-3-carbaldehyde (489 mg), copper (I) cyanide (480 mg), tris(dibenzylideneacetone)dipalladium (0) (49 mg) and 1,1′-bis(diphenylphosphino)ferrocene (89 mg) were mixed in 1,4-dioxane (20 mL), and the mixture was heated under reflux for 3 hr. The reaction mixture was allowed to cool, diluted with ethyl acetate, and filtered. The obtained filtrate was washed with a saturated aqueous sodium hydrogencarbonate solution and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=2:3→3:7) to give the title compound as a colorless oil (yield 380 mg, about 100%).
