(±)-Cis-N-(4-chloro-phenyl)-N-{1-[4-(3-hydroxy-2,2-dimethyl-propoxy)-benzoyl]-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl}-acetamide 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 (210 mg, 0.484 mmol) was dissolved in DMF (10 mL) at room temperature. Potassium carbonate (1 g, 7.1 mmol) was added, followed by 3-bromo-2,2-dimethyl-propan-1-ol (813 mg, 4.84 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 (110 mg, 44%).
