Reaction Steps

A mixture of N-(trans-4-trifluoromethyl-cyclohex-1-yl)-2-(difluoromethoxy)-5-amino-4-nitro-benzoic acid amide (70 mg, 0.176 mmol), Pd/C (15 mg) and 10 mL THF is stirred under a H2-atmosphere (3 bar) for 2 h. The crude mixture is filtered into a flask charged with N-(2,4-dichloro-3-isothiocyanato-benzyl)-2,2-dimethyl-propionamide (59 mg, 0.185 mmol) and the filter cake is washed with 40 mL THF. The mixture is stirred for 4 h at rt and overnight at 60° C. Then the reaction mixture is concentrated to −10 mL and stirred for additional 8 h at 60° C. Then it is concentrated i. vac., diluted with MeCN (2.0 mL) and DIC (29 μl, 0.186 mmol) is added and it is stirred for 4 d. Then the mixture is concentrated, diluted with DMF and THF and purified via HPLC.
