Reaction Steps

A mixture of 2.5 g (E)-3-[1-(4-Iodo-benzenesulfonyl)-1H-pyrrol-3-yl]-acrylic acid is dissolved in 140 ml DMF. To this mixture are added 0.949 g HOBtxH2O, and 6.27 g Et3N. After 30 min 3.57 g EDCxHCl are added and the resulting mixture is stirred for 30 min. Now 1.29 g of N-boc-o-phenylenediamine are added and the reaction mixture is stirred overnight. The solvent is evaporated and the residue is partitioned between ethyl acetate and water. The organic phase is dried and evaporated and the crude product is purified by silica gel flash chromatography.
