Versuchsvorschrift

To a solution of 2,6-dimethyl-4-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-aniline (145 mg, 0.5 mmol) and 2,6-dimethoxy-3-nitrobenzoic acid (136 mg, 0.6 mmol) in dichloromethane (10 ml) was added triethylamine (210 μl, 1.5 mmol) and bis(2-oxo-3-oxazolidinyl)phosphonic chloride “BOP-Cl” (153 mg, 0.6 mmol). The reaction mixture was heated to reflux for 48 hours. The reaction mixture was cooled to ambient temperature and quenched by the addition of a saturated sodium bicarbonate solution (10 ml). The phases were separated, the organic phase was dried over sodium sulfate and concentrated. Purification by chromatography over silica gel (eluent: hexane/ethyl acetate 2:1) gave N-[2,6-dimethyl-4-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-phenyl]-2,6-dimethoxy-3-nitrobenzamide (222 mg, 89% yield).
