Reaction Steps

To a solution of 4-[5-[3-(2,2-dimethoxyethyl)-6-methyl-2,4-dioxo-1-(3-trifluoromethylphenyl)-1,2,3,4-tetrahydropyrimidin-5-yl]-1H-pyrazol-1-yl]benzonitrile (prepared in Example 7) (10.0 mg) in tetrahydrofuran (0.5 ml)/water (0.1 mL) was added trifluoroacetic acid (40 μl) and the resulting mixture was stirred at 100° C. for three hours. The reaction mixture was neutralized with aqueous sodium hydroxide solution, and thereto was added water and the resulting mixture was extracted with ethyl acetate (10 ml×2). The organic layer was washed with saturated saline (10 ml), dried over anhydrous sodium sulfate and then concentrated under reduced pressure to afford 4-[5-[6-methyl-4-oxo-3-(2-oxoethyl)-1-(3-trifluoromethylphenyl)-1,2,3,4-tetrahydropyrimidin-5-yl]-1H-pyrazol-1-yl]benzonitrile (9.1 mg).
