Procedure

To 40 ml of a solution of 5.28 g of 6-chloronicotinoyl chloride in benzene, 16 g of aluminum chloride was added under ice-cooling and the resulting mixture was heated under reflux for six hours. After cooling, the reaction mixture was poured into a solution of ice/hydrochloric acid and extracted with ether. The organic phase was washed with water and dried over anhydrous sodium sulfate. After filtering off the sodium sulfate and distilling off the solvent, 4.6 g of 3-benzoyl-6-chloropyridine was obtained. m.p.: 39°-40° C.
