Procedure

A mixture of methyl 2-(3-(2-(dimethylamino)ethylcarbamoyl)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (157 mg, 0.38 mmol) in methanol (6.5 mL) and 1M sodium hydroxide aqueous solution (5.1 mL, 5.1 mmol, 13.0 eq.) was heated to reflux for 30 min, LC-MS showed the reaction was complete and only the desired product formed. The solvent was concentrate in vacuo and the residue was dissolved in water and acidified with 1 M hydrochloric acid solution to pH=6. The white precipitated solid was collected by filtration and dried in vacuo to afford 122 mg of 2-(3-(2-(dimethylamino)ethylcarbamoyl)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid as a white solid. Yield: 80.5%. MS (ESI+APCI) M+1=396.2.
