실험 절차
To a solution of 4-(4-bromo-5-(3,6-dimethyl-2,4-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,3,4-tetrahydropyrimidin-5-yl)-1H-pyrazol-1-yl)benzonitrile (prepared in Example 93) (50.4 mg) in 1,4-dioxane (1.0 ml) were added bis(tri-tert-butylphosphine)palladium (4.9 mg), N,N-diisopropylethylamine (32.0 L) and methanol (1.0 mL), and the resulting mixture was stirred at 10° C. under carbon monoxide atmosphere for four hours. To the reaction mixture was added ethyl acetate (100 ml) and the resulting mixture was washed with water (30 ml) and saturated saline (30 ml), dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate) to afford methyl-1-(4-cyanophenyl)-5-(3,6-dimethyl-2,4-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,3,4-tetrahydropyrimidin-5-yl)-1H-pyrazole-4-carboxylate (9.4 mg) as white solid.
