Reaction Steps

(±)-Cis-4-(4-{4-[(4-chloro-phenyl)-propionyl-amino]-2-methyl-3,4-dihydro-2H-quinoline-1-carbonyl}-phenoxy)-butyric acid ethyl ester was prepared from (±)-cis-N-(4-chloro-phenyl)-N-[1-(4-hydroxy-benzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-propionamide. (±)-Cis-N-(4-chloro-phenyl)-N-[1-(4-hydroxy-benzoyl)-2-methyl-1,2,3,4-tetrahydroquinolin-4-yl]-propionamide (140 mg, 0.31 mmol) was dissolved in DMF (5 mL) at room temperature. Sodium hydride (60% in oil, 32 mg, 0.81 mmol) was added and the mixture allowed to stir 30 min. Ethyl 4-bromobutyrate (207 mg, 1.06 mmol) was added and the reaction was allowed to stir over night. Ethanol was added and the reaction was concentrated in vacuo. The crude residue was purified by silica gel chromatography (80/20 hexanes/ethyl acetate-50/50 hexanes ethyl acetate gradient) to afford the product (171 mg, 0.304 mmol, 98%).
