Reaction Steps

(±)-Cis-3-(4-{4-[acetyl-(4-chloro-phenyl)-amino]-2-methyl-3,4-dihydro-2H-quinoline-1-carbonyl}-phenoxy)-2,2-dimethyl-propionic acid methyl 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-tetrahydro-quinolin-4-yl]-propionamide (400 mg, 0.92 mmol) was dissolved in DMF (25 mL) at room temperature. Potassium carbonate (1 g, 7.1 mmol) was added, followed by 3-bromo-2,2-dimethyl-propionic acid methyl ester (400 mg, 0.92 mmol), the reaction was heated to 95° C. and stirred over night. The reaction mixture was cooled to room temperature, filtered and concentrated in vacuo. The crude product was purified by silica gel chromatography (95/5 dichloromethane/ethyl acetate—70/30 dichloromethane/ethyl acetate) to afford the pure ester (40 mg, 8%).
