실험 절차

EDCI (1.09 g, 5.65 mmol) was added to a suspension of 5-Carboxy-2-chloro-6H-thieno[2,3-b]pyrrole (Method 9, 1.04 g, 5.13 mmol) and (3-amino-2-oxo-3,4-dihydroquinolin-1(2H)-yl)acetonitrile (Method 13; 1.29 g, 5.13 mmol) in DCM (30 mL) and the reaction stirred for 18 hours. The reaction was evaporated and the residue was partitioned between DCM:MeOH (9:1) (100 mL) and aqueous K2CO3 (25 mL). The organic layer was then separated, dried (MgSO4), filtered and evaporated. The residue was purified by column chromatography (DCM to DCM:MeOH (9:1)) to give a brown solid. The solid was triturated with refluxing Et2O (25 mL) and the solid filtered, washed with Et2O (25 mL) then hexane (25 mL) to afford the title compound (414 mg, 21%) as a pale brown solid.
