実験手順

A mixture of 5-phenylcyclohexane-1,3-dione (1.51 g, 8.04 mmol), 3-(trifluoromethyl)-aniline (1.00 mL, 1.29 g, 8.04 mmol), Ytterbium(III) trifluormethanesulfonate (25 mg, 40 μmol, 0.5 mol %) and N,N-dimethylformamide (2.5 mL) is stirred at room temperature over night. Methanol and water are added and the mixture is filtered. The precipitate is dissolved in a mixture of N,N-dimethylformamide, methanol and some drops of aqueous ammonia. Water is added and the precipitate is filtered. Yield: 1.51 g; ESI mass spectrum [M+H]+=332, Retention time HPLC: 1.09 min (Z003—001).
