実験手順

To a solution of 1-(4-cyanophenyl)-5-(3,6-dimethyl-2,4-dioxo-1-(3-trifluoromethylphenyl)-1,2,3,4-tetrahydropyrimidin-5-yl)-1H-pyrazole-4-carboxylic acid (prepared in Example 132) (153 mg) in acetonitrile (5 ml) was added 4-dimethylaminobutanol (0.21 ml), 1-hydroxy-7-azabenzotriazole (126 mg) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (177 mg) and the resulting mixture was stirred at room temperature for sixteen hours. To the reaction solution were added saturated aqueous sodium hydrogen carbonate solution (10 ml) and ethyl acetate (20 ml×2) such that the intended products were extracted into an organic layer. The organic layer was washed with saturated saline (20 ml), dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: chloroform/methanol) to afford 4-(dimethylamino)butyl 1-(4-cyanophenyl)-5-(3,6-dimethyl-2,4-dioxo-1-(3-trifluoromethylphenyl)-1,2,3,4-tetrahydropyrimidin-5-yl)-1H-pyrazole-4-carboxylate (137 mg). UPLC/MS 595 (M+H)/0.73 min (measurement condition 9)
