Versuchsvorschrift
According to the previously described general procedure (GP1), Knoevenagel condensation (75° C.; 3h20) between 2-fluoro-4-(trifluoromethyl)benzaldehyde (5.000 g; 26.027 mmol) and malonic acid (5.145 g; 49.451 mmol) gave the product 3-(2-fluoro-4-trifluoromethyl-phenyl)-acrylic acid as a colorless solid (5.030 g; 82.5%). LC-MS: tR=0.89 min; [M+H]+: no ionisation.
