Reaction Steps
A mixture of methyl 2-(3-(isopropylcarbamoyl)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (120 mg, 0.315 mmol) in methanol (4.8 mL) and 2N sodium hydroxide aqueous solution (3.2 mL, 6.4 mmol) was heated to reflux for 2 h. Thin layer chromatography (petroleum ether:ethyl acetate=3:1) and 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=6, extracted with ethyl acetate/tetrahydrofuran, washed with brine and dried over anhydrous sodium sulfate. Removal of the solvent in vacuo gave 92 mg of 2-(3-(isopropylcarbamoyl)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid as a white solid. Yield: 80%. LC-MS (M+1)=367.2.
