실험 절차
Ethyl 2-(2-methyl-3,4,6-trifluorobenzoyl)-3-ethoxyacrylate (3.5 g) is dissolved in ethanol (25 ml) and thereto cyclopropylamine (0.84 ml) is added dropwise under ice-cooling. After stirring at room temperature for 30 minutes, the mixture is concentrated and the residue is purified with column chromatography (silica-gel, dichloromethane: n-hexane =1: 1) to give ethyl 2-(2-methyl-3,4,6-trifluorobenzoyl)-3-cyclopropylaminoacrylate (2.7 g).
