Versuchsvorschrift

Sodium tert-butoxide (126 mg, 1.32 mmol) is added to a solution of 1-((4-cyanophenyl)-(2-ethoxy-6-oxo-4-(3,4,5-trimethoxyphenyl)cyclohex-1-enyl)methyl)-3-(3-(trifluoromethyl)phenyl)urea (intermediate 19, 684 mg, 1.10 mmol) in acetonitrile (8 mL) and the mixture is stirred at room temperature for 2 h. Water is added and the mixture is extracted with ethyl acetate. The organic layer is dried over Na2SO4 and concentrated under reduced pressure. The residue is purified by reversed phase HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 190 mg; ESI mass spectrum [M+H]+=578, Retention time HPLC: 1.13 min, 1.14 min (1:1 mixture of diastereomers) (V011_S01).
