Procedure

A mixture of 3.1 g (E)-3-[1-(4-bromo-benzenesulfonyl)-1H-pyrrol-3-yl]-acrylic acid with 170 ml DMF and 1.3 g HOBt.H2O and 12.0 ml triethylamine is stirred for 0.5 h. Then 4.9 g EDC.HCL is added and the suspension is stirred again at ambient temperature for 0.5 h. After that 1.8 g (2-amino-phenyl)-carbamic acid tert-butyl ester are added and the mixture is stirred at ambient temperature for 24 h. The DMF is evaporated and the residue is extracted with ethyl acetate and water. The organic layer is dried over sodium sulfate. The title compound is isolated by flash chromatography.
