Procedure

To a vial containing 4-chloro-5-nitro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (714.2 mg, 2.115 mmol) and tert-butyl (3S)-piperidin-3-ylcarbamate (Combi-Blocks, 645.9 mg, 3.225 mmol), 1-butanol (8.00 mL) was added followed by DIPEA (582.8 mg, 4.509 mmol). The reaction 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 (0-50% EtOAc in hexanes) to give the sub-title compound as a yellow solid (719.5 mg, 68%). LCMS calc. for C23H28N5O6S (M+H)+: m/z=502.2. found 502.2.
