Reaction Steps

Diisopropylethylamine (0.40 mL, 2.17 mmol), (2-(7-Aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate) (0.28 mg, 0.72 mmol) was added to a solution of [1-(2-methoxy-ethyl)-3-thiophen-3-yl-1H-pyrrol-2-yl]-oxo-acetic acid (200 mg, 0.72 mmol) in dry dichloromethane at room temperature and the reaction mixture stirred for 1 h. 4-[4-(4,6-Dimethyl-pyridin-2-yl)-piperazin-1-yl]-phenylamine (160 mg, 0.56 mmol) was added and the mixture was then heated in a sealed tube at 90° C. for 18 h. The reaction mixture was cooled to room temperature, washed with water and brine. The organic layer was dried over anhydrous sodium sulfate and evaporated under reduced pressure to give crude compound which was purified by preparative HPLC to afford N-{4-[4-(4,6-dimethyl-pyridin-2-yl)piperazin-1-yl]-phenyl}-2-[1-(2-methoxy-ethyl)-3-thiophen-3-yl-1H-pyrrol-2-yl]-2-oxo-acetamide (80 mg, 20%) as a solid.
