Versuchsvorschrift

(1-Chloro-2-methyl-propenyl)-dimethylamine (102 μl) is added to a mixture of 2-(difluoro-methoxy)-5-amino-4-nitro-benzoic acid (175 mg, 0.705 mmol, prepared in analogy to WO2010/034797), 5 mL THF and 10 mL DCM and it is stirred for 5 h. Then trans-4-trifluoromethyl-cyclohexylamine (158 mg, 0.776 mmol) and pyridine (139 μL, 1.77 mmol) are added and it is stirred overnight. The solvent is removed i. vac., half-saturated aq. NaHCO3— solution is added and it is extracted with DCM. The organic layers are dried with Na2SO4, filtered, concentrated and purified via preparative HPLC (Method F).
