Versuchsvorschrift

Grubbs catalyst 2nd generation (124 mg) was added to a solution of methyl 4-(3-butenoyl)-3-(2-ethoxycarbonylvinyl)-5-(3,4,5-trifluorophenyl)piperazine-1-carboxylate (643 mg) in methylene chloride (50 mL), and the reaction solution was heated under reflux for one hour. The reaction solution was left to cool to room temperature. Then, triethylamine (0.2 mL) was added to the reaction solution, which was then stirred at room temperature for 20 minutes. The reaction solution was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate) to obtain 174 mg of the title compound. The property values of the compound are as follows.
