Procedure

To (methoxymethyl)triphenylphoshonium chloride (1.74 g) and tertiary-butoxy potassium (853 mg) was added at 0° C. glyme/toluene (10 ml/10 ml) and the resulting mixture was stirred for fifteen minutes. To the reaction mixture was added at 0° C. (R)-4-(5-(6-methyl-2,4-dioxo-3-(1-oxopropane-2-yl)-1-(3-trifluoromethylphenyl)-1,2,3,4-tetrahydropyrimidin-5-yl)-1H-pyrazol-1-yl)benzonitrile (prepared in Example 373) (500 mg) and the resulting mixture was stirred at room temperature for fifteen hours. To the reaction mixture was added water (20 ml) followed by an addition of ethyl acetate (30 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 sodium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate) to afford (R)-4-(5-(3-(4-methoxy-3-buten-2-yl)-6-methyl-2,4-dioxo-1-(3-trifluoromethylphenyl)-1,2,3,4-tetrahydropyrimidin-5-yl)-1H-pyrazol-1-yl)benzonitrile (350 mg). UPLC/MS 522 (M+H)/1.00 min. (measurement condition 9)
