Triethylamine (38 μL, 0.27 mmol) then ethyl chloroformate (26.1 μL, 0.27 mmol) were added to N-[1-(carboxymethyl)-2-oxo-1,2,3,4-tetrahydroquinolin-3-yl]-2-chloro-6H-thieno[2,3-b]pyrrole-5-carboxamide (Example 2; 100 mg, 0.25 mmol) in anhydrous THF (2 mL) at 0° C. followed by stirring for 1 h. Concentrated aqueous NH3 (1 mL) was added and the reaction was stirred for a further 1 h. Water (20 mL) and EtOAc (40 mL) were added and the organic layer was separated, washed with 1M HCl (20 mL) and the organic layer was dried (MgSO4), filtered and evaporated. The residue was purified by column chromatography (MeOH:DCM 1:19) to afford the title compound (56 mg, 56%) as a white solid.
