Versuchsvorschrift

To a stirring mixture of the 2-(4-tert-butylbenzoyl-amino)benzoic acid (9.5 g, 32 mmol), CH2Cl2 (200 mL) and 2 drops of DMF was added 2 M oxalyl chloride in CH2Cl2 (19 mL). After stirring at ambient temperature for 45 minutes, the mixture was concentrated under vacuum to an oil, redissolved in 100 mL CH2Cl2 and cooled to 0° C. To this was added triethylamine (3.3 g, 33 mmol) at 0° C. for 1 hour. The solvent was removed in vacuo and the residue purified by flash chromatrography using hexanes/EtOAc to give 8.6 g (96%) of a white powder.
