Reaction Steps

A solution of 3-(1H-Pyrrolo[2,3-b]pyridin-4-ylamino)-thiophene-2-carboxylic acid (2-benzylamino-ethyl)-amide (95 mg, 0.24 mmol), diisopropylethylamine (84 uL, 0.49 mmol) and acetyl chloride (25 uL, 0.37 mmol) in tetrahydrofuran (2.0 mL) was stirred at room temperature for 18 h. The solution was concentrated in vacuo then purified by ISCO Companion (silica, 10% methanol, methylene chloride, 1% ammonium hydroxide) to afford 3-(1H-Pyrrolo[2,3-b]pyridin-4-ylamino)-thiophene-2-carboxylic acid [2-(acetyl-benzyl-amino)-ethyl]-amide (25 mg, 24%). LCMS (ESI) 434 (M+H) 1H NMR (400 MHz, DMSO-d6) δ ppm 11.56 (1H, br. s.) 10.16-10.43 (1H, m) 8.15 (0H, t, J=5.00 Hz) 8.02 (1H, t, J=2.71 Hz) 7.72-7.86 (1H, m) 7.44-7.54 (1H, m) 7.13-7.39 (6H, m) 6.83 (1H, dd, J=12.23, 5.49 Hz) 6.36-6.50 (1H, m) 4.49-4.61 (2H, m) 3.34-3.50 (4H, m) 1.91-2.19 (3H, m)
