EDCI (166 mg, 0.87 mmol) and HOAt (11 mg, 0.08 mmol) were added at 0° C. to a reaction mixture of 4-methyl-1-(4-methylbenzyl)-3-p-tolyl-1H-pyrrole-2-carboxylic acid (252 mg, 0.79 mmol) and 1-(2-diethylaminoethyl)-piperazine (146 mg, 0.79 mmol) in DCM (5 mL) and the reaction mixture was stirred for 30 min at 0° C. and overnight at RT. After removal of the solvent, purification proceeded by means of column chromatography and the desired product [4-(2-diethylamino-ethyl)-piperazin-1-yl]-[4-methyl-1-(4-methylbenzyl)-3-p-tolyl-1H-pyrrol-2-yl]-methanone (148 mg, 38% of theoretical) was obtained.
