A mixture of 4-chloro-3-nitrobenzoyl chloride (22.0 g, 0.1 mol) and 2-amino-5-bromopyridine (17.3 g, 0.1 mol) in toluene (250 mL) was refluxed for 4 hours, allowing gaseous HCl to escape the reaction vessel through an open, water cooled condenser. The reaction mixture was cooled to room temperature, diluted with hexanes (200 mL) and filtered to give the title compound (33.9 g, 95%).
