Procedure
Propionyl chloride (6.32 mL, 1.3 eq) and triethylamine (11.69 mL, 1.5 eq) were added sequentially to a solution of 3-amino-4-chloroquinoline (10.0 g, 1.0 eq) in dichloromethane (200 mL). The reaction mixture was stirred overnight and then quenched with aqueous saturated sodium bicarbonate. The organic layer was separated, dried over magnesium sulfate, and then concentrated under reduced pressure. The residue was purified by column chromatography (silica gel eluting with 2% methanol in dichloromethane) to provide 5.8 g of N-(4-chloroquinolin-3-yl)propionamide.
