Procedure

A mixture of methyl 2-(3-(2-methoxyethylcarbamoyl)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (100 mg, 0.25 mmol) in methanol (4.5 mL) and 1N sodium hydroxide aqueous solution (3.7 mL, 3.7 mmol) was heated to reflux for 1 h. LC-MS showed the reaction was complete. The solvent was removed in vacuo to give white solid, which was dissolved in water and acidified with 1N hydrochloric acid solution to pH=2. The precipitated white solid was collected by filtration and washed with water, dried in vacuo to afford 69 mg of 2-(3-(2-methoxyethylcarbamoyl)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid. Yield: 71.9%. LC-MS (M+1)=383.2.
