실험 절차

To a solution of 3-(2,5-dimethylpyrrol-1-yl)-1H-pyrazole (1.00 g) prepared according to the same procedures as Preparation 4 in N-methylpyrrolidone (10 ml) were sequentially added 1-fluoro-2-iodobenzene (1.08 ml), copper (I) oxide (89 mg), 8-quinolinol (180 mg) and cesium carbonate (4.04 g) at room temperature, and the mixture was stirred at 110° C. for 3 hours. This reaction mixture was cooled to room temperature, and then toluene was added thereto, and the mixture was filtered through Celite. The filtrate was sequentially washed with a 2N aqueous solution of sodium hydroxide, water and a saturated aqueous solution of sodium chloride, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=1/0 to 10/1) to give the titled compound (1.19 g).
