実験手順

To a stirred solution of methyl 2-(3-(N,N-dimethylsulfamoyl)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (149 mg, 0.37 mmol) in methanol/tetrahydrofuran (5 mL/5 mL) was added 1N sodium hydroxide (5.6 mL). The resultant mixture was heated to reflux for 2.5 h. Organic solvent was removed and the residue was dissolved in water. The aqueous layer was acidified to pH=4. The precipitates were filtered, and dissolved in tetrahydrofuran, dried over anhydrous magnesium sulfate. Anhydrous magnesium sulfate was removed, and after evaporation, the residue was treated with ethyl acetate to afford 29 mg of 2-(3-(N,N-dimethylsulfamoyl)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid. (Yield: 20%). MS (ESI+APCI) M+1=389.1.
