Reaction Steps

To a solution of nicotinoyl chloride (0.500 g, 2.84 mmol) in 15 mL of 1,2-dichloroethane was added 4-chloroaniline (0.432 g, 3.41 mmol) and triethylamine (0.400 mL, 2.84 mmol), respectively. The reaction mixture was stirred at room temperature for 1 h before it was washed with water (2×), brine (1×), dried over Na2SO4, and the solvent removed in vacuo. The crude material was purified by chromatography over silica, using an eluent of 2% (2 M NH3 in methanol) in chloroform, to afford the amide (0.758 g, 100%).
