Versuchsvorschrift

6M Aqueous HCl (1.47 mL) was added to N-{1-(2,2-dimethyl-1,3-dioxolan-4-ylmethyl)-2-oxo-1,2,3,4-tetrahydroquinolin-3-yl}-2-chloro-6H-thieno[2,3-b]pyrrole-5-carboxamide (Method 3; 340 mg, 7.45 mmol) in THF (14 mL) and the reaction was stirred for 4 h. The reaction was quenched by addition of triethylamine (1.5 mL) then diluted with water (30 mL) and EtOAc (40 mL). The organic layer was separated, dried (MgSO4), filtered and evaporated. The residue was triturated with hot Et2O (10 mL) and after cooling was filtered and dried to afford the title compound (260 mg, 83%) as white solid.
