Reaction Steps

Ethyl 1-allyl-4-(2-fluoro-4-iodoanilino)-6-oxo-1,6-dihydro-3-pyridinecarboxylate was dissolved in EtOH and treated with 1 M NaOH, as for example 1, step C, to hydrolyse the ester to give 1-allyl-4-(2-fluoro-4-iodoanilino)-6-oxo-1,6-dihydro-3-pyridinecarboxylic acid as a white solid (99%), used directly in the next step. 1H NMR [(CD3)2SO, 400 MHz] δ 13.25 (v br s, 1H), 9.73 (br s, 1H), 8.41 (s, 1H), 7.75 (dd, J=10.1, 1.9 Hz, 1H), 7.60 (ddd, J=8.4, 2.0, 0.8 Hz, 1H), 7.32 (t, J=8.5 Hz, 1H), 5.98-5.86 (m, 1H), 5.49 (d, J=1.1 Hz, 1H), 5.19 (dd, J=10.3, 1.4 Hz, 1H), 5.14 (ddd, J=17.1, 3.0, 1.5 Hz, 1H), 4.52 (d, J=5.6 Hz, 2H). HRMS (EI+) calcd C15H12FIN2O3 (M+) 413.9877, found 413.9874.
