Reaction Steps

4-aminooxindole (80 mg, 0.54 mmol) was made to react to 1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (125.5 mg, 0.54 mmol) in the presence of O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium tetrafluoroborate (TBTU, 250 mg, 0.78 mmol) and triethylamine (TEA, 0.23 mL, 1.62 mmol) in a mixture of dry DMF and acetonitrile (1:3, 6 mL) under rt for 14 hours. Resultant solid was collected by filter, washed by methanol, water and ether, and dried to give 1-(4-fluorophenyl)-2-oxo-N-(2-oxoindolin-4-yl)-1,2-dihydropyridine-3-carboxamide: YD: 56%; mp: 293-295° C. 1H-NMR (400 MHz, DMSO-d6): 11.77 (s, 1H), 10.41 (s, 1H), 8.58 (dd, J=7.6, 2 Hz, 1H), 8.10 (dd, J=6.6, 2 Hz, 1H), 7.77 (d, J=8.4 Hz, 1H), 7.59 (m, 2H), 7.41 (d, J=8.8 Hz, 2H), 7.17 (dd, J=8, 7.6 Hz, 1H), 6.71 (dd, 7.6, 6.6 Hz, 1H), 6.68 (d, J=7.6 Hz, 1H), 3.36 (s, 2H).
