Procedure

Sodium tert-butoxide (211 mg, 2.19 mmol) is added to a solution of 1-((4-cyanophenyl)-(2-ethoxy-6-oxo-4-(4-(trifluoromethyl)phenyl)cyclohex-1-enyl)methyl)-3-(3-(trifluorometh yl)phenyl)urea (intermediate 17, 825 mg, 1.37 mmol) in acetonitrile (12 mL) and the mixture is stirred at room temperature over night. 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 flash chromatography on silica (gradient cyclohexane/ethyl acetate 100:0 to 0:100). Yield: 135 mg; ESI mass spectrum [M+H]+=556, Retention time HPLC: 1.27 min, 1.29 min (1:1 mixture of diastereomers) (V011_S01).
