Reaction Steps

To a solution of ethyl 2-aminobenzoate (5 g) in pyridine (50 mL) was added 4-chlorobutanoyl chloride (3.6 mL) at 0° C., and the mixture was warmed to room temperature and stirred overnight. The reaction mixture was poured into water, and the mixture was partitioned twice with ethyl acetate. The organic layers were combined, and the mixture was washed with brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (8.03 g).
