Participants

Reaction Steps

A mixture of 2,6-dichloro-N-(2-chloro-3-fluoro-pyridin-4-yl)-4-cyano-benzamide (1.2 g, 3.4 mmol) and thionyl chloride (12.5 mL) was heated under reflux for 18 hours then cooled to ambient temperature. The reaction mixture was diluted with toluene (10 mL) and concentrated to dryness under reduced pressure to afford the title compound as a white solid (1.23 g, 97% yield). 1H NMR (400 MHz, CDCl3): δ 8.25 (d, J=5.1 Hz, 1H), 7.75 (s, 2H), 6.97 (t, J=5.1 Hz, 1H).
