Versuchsvorschrift
10.5 g of 4-(trifluoromethoxy)benzaldehyde, 5.72 g of malonic acid, 8.5 g of ammonium acetate and 40 ml of ethanol are boiled under reflux for 8 hours and stirred at room temperature overnight. The cooled reaction mixture is then filtered with suction, washed with ethanol and ether and dried in air. 3-amino-3-(4-trifluoromethoxyphenyl)propionic acid is obtained, melting point 258-260°.
