Reaction Steps

(Step 1) To a solution of 2-amino-5-chlorobenzonitrile (5.0 g) and dimethylaminopyridine (0.12 g) in dimethylacetamide (25 ml) was added propionyl chloride (3.4 ml) at room temperature, and the mixture was stirred overnight. The reaction mixture was poured into water, and extracted twice with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate, and filtered. The solvent was evaporated under reduced pressure. The residue was recrystallized from ethanol and diisopropyl ether to give N-(4-chloro-2-cyanophenyl)propanamide (5.7 g).
