Procedure

TBAF (1.0 M in THF, 4.92 mL, 4.92 mmol) was added to N-[1-(3-{[tert-butyl(dimethyl)silyl]oxy}propyl)-2-oxo-1,2,3,4-tetrahydroquinolin-3-yl]-2-chloro-6H-thieno[2,3-b]pyrrole-5-carboxamide (Method 20, 1.84 g, 3.56 mmol) in THF (15 mL) and the reaction was stirred for 48 hours. The reaction was quenched by the addition of EtOAc (50 mL) and NH4Cl (aq.) (20 mL) and the organic layer was dried (MgSO4), filtered and evaporated. Purification by column chromatography afforded the title compound (1.24 g, 3.08 mmol, 86%) as a white solid.
