Reaction Steps

To 4-cyano-2-fluoro-N-(2-methoxy-4-pyridyl)benzamide (7.3 g, 26.99 mmol) in acetonitrile (244.0 mL) was added TMSI (9.99 mL, 70.17 mmol). The reaction was stirred at 50° C. overnight. The acetonitrile was evaporated and the crude solid was triturated with ethyl acetate. The solid was isolated by filtration and washed with ethyl acetate to give 4-cyano-2-fluoro-N-(2-oxo-1H-pyridin-4-yl)benzamide as a tan solid. ESI-MS m/z calc. 257.06. found 258.1 (M+1)+; Retention time: 1.08 minutes (3 minutes run). 1H NMR (400 MHz, DMSO-d6) δ 10.94 (s, 1H), 8.11 (t, J=11.4 Hz, 1H), 7.88 (m, 2H), 7.53 (d, J=7.1 Hz, 1H), 7.01 (d, J=2.0 Hz, 1H), 6.60 (dd, J=7.2, 2.1 Hz, 1H) ppm.
