実験手順

To a solution of 4-(5-(3-ethyl-6-methyl-2,4-dioxo-1-(3-trifluoromethylphenyl)-1,2,3,4-tetrahydropyrimidin-5-yl)-4-iodo-1H-pyrazol-1-yl)benzonitrile (prepared in Example 268) (98.1 mg) in N,N-dimethy formamide (1.0 ml) were added palladium dibenzylidene acetone complex (15.9 mg), 1,1′-bis(diphenylphosphino)ferrocene) (18.9 mg), N,N-diisopropylethylamine (33.8 μl) and sodium methanethiolate (13.4 mg) and the resulting mixture was stirred at 110° C. for four hours. The reaction mixture was diluted with ethyl acetate (50 ml) and washed with saturated saline (20 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 4-(5-(3,6-dimethyl-2,4-dioxo-1-(3-trifluoromethylphenyl)-1,2,3,4-tetrahydropyrimidin-5-yl-4-(methylthio)-1H-pyrazol-1-yl)benzonitrile (57.4 mg).
