Versuchsvorschrift

5-Carboxy-2,3-dichloro-4H-thieno[3,2-b]pyrrole (Method 4; 2.36 g, 10.0 mmol), trans-2-amino-1-{N-[(1,1-dimethylethoxy)]carbonylamino}indan (Method 6; 2.5 g, 10.0 mmol), DIPEA (1.7 ml, 10.0 mmol) and HOBT (1.35 g, 10.0 mmol) was stirred in DCM (75 ml) at room temperature for 2 minutes. EDCI (2.4 g, 12.5 mmol) was added and the mixture stirred at room temperature for 20 hours during which time the product precipitated. The reaction was filtered, washed with DCM (2×25 ml) and dried to give the title compound (3.7 g, 80%) as a pale green powder.
