Reaction Steps

To a solution of o-chloroaniline (0.68 g, 5.3 mmol) in 20 mL of PhMe was added 3 mL of AlMe3. The mixture was stirred at ambient temperature for 0.5 h and added into a solution of ethyl 5-ethoxypyridine-2-carboxylate 3 (0.26 g, 1.33 mmol) in 10 mL of PhMe. The mixture was stirred at ambient temperature for 15 h and quenched with 20 mL of 1N HCl. The mixture was extracted with ethyl acetate. The organic layer was separated and concentrated. The residue was purified by column (2:1 of hexane/ethyl acetate) to give N-(2-chlorophenyl)-5-ethoxypyridine-2-carboxamide 4 as a solid. Yield: 310 mg, 96%.
