Butyric acid (0.029 ml, 0.321 mmol), diisopropylethylamine (0.065 ml, 0.375 mmol), and HATU (0.122 g, 0.321 mmol) were added sequentially to a solution of 3-[4-(5-amino-1-benzenesulfonyl-1H-pyrrolo[2,3-b]pyridin-4-ylamino)-piperidin-1-yl]-propionitrile (0.130 g, 0.306 mmol, prepared as described in Example 118) in a 4:1 mixture of CH2Cl2 and DMF (5 ml) at 25° C. The reaction mixture was stirred for 15 h at 25° C., then was partitioned between saturated NaHCO3 (6 ml) and CH2Cl2 (2 ml). The phases were separated using a phase separation column (Biotage) and the organic layer was concentrated under reduced pressure to give crude N-{1-benzenesulfonyl-4-[1-(2-cyano-ethyl)-piperidin-4-ylamino]-1H-pyrrolo[2,3-b]pyridin-5-yl}-butyramide as a brown oil. LCMS (Method G, ESI): RT=0.59 min, m+H=495.3. This material was used in the next step below without additional purification or characterization.
