Reaction Steps

A mixture of 1-benzenesulfonyl-4-chloro-5-nitro-1H-pyrrolo[2,3-b]pyridine (0.6769 g, 2.004 mmol), (S)-3-amino-1-Boc-piperidine (0.4269 g, 2.132 mmol), and diisopropylethylamine (0.45 mL, 2.6 mmol) in propan-2-ol (12 ml) was heated in a microwave reactor at 110° C. for 20 minutes. The solvent was evaporated in vacuo and then purified by column chromatography on silica gel (gradient: 0 to 30% ethyl acetate in heptanes) affording 853.7 mg (85%) of (S)-3-(1-Benzenesulfonyl-5-nitro-1H-pyrrolo[2,3-b]pyridin-4-ylamino)-piperidine-1-carboxylic acid tert-butyl ester. LCMS (Method F, ESI): RT=1.19 min, m+H=502.3.
