Versuchsvorschrift

A mixture of methyl 2-(3-carbamoylphenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxy late (84 mg, 0.25 mmol) in methanol (4.5 mL) and 1 M sodium hydroxide aqueous solution (3.2 mL, 3.2 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 concentrated 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 50 mg of 2-(3-carbamoylphenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid as a white solid. Yield: 62.1%. MS (ESI+APCI) M+1=325.1.
