실험 절차

To a solution of 1-(4-fluorophenyl)-5-iodo-1H-pyrazol-3-ylamine (38 mg) prepared in Preparation 18 in 1,4-dioxane (0.4 ml) were sequentially added 2-[3-fluoro-5-((R)-2,2,2-trifluoro-1-methylethoxymethyl)phenyl]-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (52 mg) prepared according to the same procedures as Preparation 15, palladium (II) acetate (3 mg), tricyclohexylphosphine (7 mg) and a 2M aqueous solution of potassium carbonate (0.2 ml) at room temperature, and the mixture was stirred at 105° C. for 4 hours. After removing an aqueous layer of the reaction mixture, an organic layer was filtered through silica gel (5 g), and subjected to elution with ethyl acetate. The filtrate was concentrated under reduced pressure, the resulting residue was purified by silica gel thin-layer chromatography (eluent: n-hexane/ethyl acetate=1/1) to give the titled compound.
