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) (139.8 mg) in 1,4-dioxane (2.0 ml) were added tetrakis(triphenylphosphine)palladium (30.7 mg),N,N-diisopropylethylamine (46.8 μl) and water (0.5 ml) and the resulting mixture was stirred at 100° C. under carbon monoxide atmosphere for four hours. To the reaction mixture was added ethyl acetate (100 ml) and the mixture was washed with 1M hydrochloric acid (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: chloroform/methanol) to afford 1-(4-cyanophenyl)-5-(3,6-dimethyl-2,4-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,3,4-tetrahydropyrimidin-5-yl)-1H-pyrazole-4-carboxylic acid (24.5 mg) as brown solid.
