Procedure

A mixture of methyl 2-(4-(cyclohex-1-enecarboxamido)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (217 mg, 0.52 mmol) in methanol (3 mL) and water (1.5 mL) was treated with a solution of sodium hydroxide (353 mg, 2.63 mmol) in water (1.5 mL) was heated to reflux until the completion of the reaction (monitored by Thin layer chromatography). The methanol was removed under vacuum. The residue was acidified with 2M hydrochloric acid to pH=1. The precipitates were collected by filtration to afford 100 mg of 2-(4-(cyclohex-1-enecarboxamido)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid as a yellow solid Yield: 53%. MS (ESI+APCI) M+1=405.2.
