Versuchsvorschrift

4-Trifluoromethyl-α-carboxybenzylamine (1.4 g, 1.83 mmol) and thionylchloride were added to methanol (8 ml) and the mixture was refluxed for 2 h. The solvent was evaporated under reduced pressure. The residue was suspended in diethyl ether and the product was filtered off, washed with ether and dried to give the title compound 0.34 g (69%).
