Pyridine → N-(4-bromo-2-chlorophenyl)-3-chloropropanamide

Participants

Reaction Steps

To a solution of 4-bromo-2-chloro-phenylamine (32 g, 0.15 mol) and pyridine (13.45 g, 0.17 mol) in DCM (200 mL) was added 3-chloropropionyl chloride (21.65 g, 0.17 mol) dropwise at 15° C. After stirring at room temperature for 1 hour, the mixture was washed with water and then hydrochloric acid (2 N, aqueous). The organic layer was dried over anhydrous Na2SO4, filtered, and concentrated in vacuo to afford title compound (10.9 g, yield: 90%) as a white solid.
