Procedure

To a vial containing 7-chloro-6-nitrothieno[3,2-b]pyridine (128.7 mg, 0.5996 mmol) and tert-butyl (3S)-piperidin-3-ylcarbamate (Combi-Blocks, 297.6 mg, 1.486 mmol), 1-butanol (3.00 mL) was added, followed by DIPEA (179.9 mg, 1.392 mmol). The mixture was stirred at 110° C. for 12 h. After cooling to room temperature, the reaction mixture was concentrated under reduced pressure. The resulting residue was purified by chromatography on silica gel (0-30% EtOAc in hexanes) to give the sub-title compound as a yellow solid (210.1 mg, 93%). LCMS calc. for C17H23N4O4S (M+H)+: m/z=379.1. found 379.2.
