Reaction Steps

1-(3,4-Difluoro-benzyl)-2-oxo-1,2-dihydro-pyridine-3-carboxylic acid 3-(1-benzenesulfonyl-5-cyano-1H-pyrrolo[2,3-b]pyridin-3-yl)-benzylamide (128 mg, 0.000201 mol) was dissolved in methanol (4.5 mL; Fisher) and water (1.5 mL, Fisher). To this was added potassium carbonate (129 mg, 0.000933 mol; Fisher) and the reaction was heated at reflux for 1 hour. The reaction was evaporated, taken up in N,N-dimethylformamide, neutralized with TFA (200 uL) and purified by preparative HPLC chromatography to yield the product in 26.9 mg yield (22%). 1H NMR (400 MHz, DMSO-d6) d ppm 12.582 (s (br), 1H) 10.078 (t, J=5.7 Hz, 1H) 8.804 (s, 1H) 8.648 (s, 1H) 8.405 (d, J=7.2 Hz, 1H) 8.224 (d, J=6.4 Hz, 1H) 8.098 (d, J=1.8 Hz, 1H) 7.750 (s, 1H) 7.639 (d, J=8.0 Hz, 1H) 7.470-7.334 (m, 3H) 7.236 (d, J=7.4 Hz, 1H) 7.183-7.128 (m, 1H) 6.589 (t, J=7.2 Hz, 1H) 5.212 (s, 2H) 4.596 (d, J=6.0 Hz, 2H); MS m/z=496.02 M+H.
