Participants

Reaction Steps

A mixture of 2-chloro-N-(3,5-difluoropyridin-4-yl)-6-nitrobenzamide (5.25 g, 16.7 mmol) in thionyl chloride (40 mL) was heated under reflux for 18 hours under a nitrogen atmosphere. After cooling to room temperature, the volatiles were removed under reduced pressure and the resultant residue was azeotroped with toluene (×3) to afford the title compound as a yellow/brown solid (5.5 g, quantitative). LCMS (Method D): RT=3.77 min, m/z: 332 [M+H+].
