Versuchsvorschrift

Under an atmosphere of argon, 4-(2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-2,3,4,5,6,7-hexahydro-1H-cyclopenta[d]pyrimidin-4-yl)benzonitrile (example 1, 200 mg, 0.50 mmol) is added to a suspension of sodium hydride (60% in mineral oil, 24 mg, 0.60 mmol) in dry tetrahydrofuran. After 20 min, methyl iodide (41 μL, 0.66 mmol) is added. After 20 min water is added and the mixture is concentrated. The residue is purified by flash a) chromatography on silica (gradient cyclohexane/ethyl acetate 1:1 to ethyl acetate). Yield: 49 mg; ESI mass spectrum [M+H]+=412; Retention time HPLC: 0.59 min (X012_S01).
