Versuchsvorschrift

4-Dimethylaminopyridine (5 mg, 0.038 mmol) and 4-hydroxypiperidine (42 mg, 0.41 mmol) were added to a suspension of N-[1-(carboxymethyl)-2-oxo-1,2,3,4-tetrahydroquinolin-3-yl]-2-chloro-6H-thieno[2,3-b]pyrrole-5-carboxamide (Example 2; 150 mg, 0.38 mmol) and EDCI (79 mg, 0.41 mmol) in THF (0.5 mL) under an inert atmosphere. DMF (0.5 mL) was added and the mixture stirred at ambient temperature for 18 h. After pouring into water (10 mL) the resultant solid was filtered off and washed with 1M HCl aq. and water. Chromatography on silica gel (eluent gradient of CH2Cl2 to MeOH:CH2Cl2 (1:9)) afforded the title compound (109 mg, 59%) as an off white solid.
