Procedure

To a stirred solution of methyl 3,3-dimethyl-2-(3-(N-methylsulfamoyl)phenyl)-1,2,3,4-tetrahydroquinoline-6-carboxylate (75 mg, 0.19 mmol) in tetrahydrofuran/methanol (2.5 mL/2.5 mL) was added 1M sodium hydroxide aqueous solution (2.89 mL, 2.89 mmol). The mixture was heated to reflux and stirred for 1.5 h. LC-MS indicated that 2005467-012-01 was consumed. The mixture was concentrated and the residue was dissolved in water. The aqueous layer was basified to pH=4 by 1M hydrochloric acid solution. The precipitated solid was filtered, and dried to give 56.7 mg of 3,3-dimethyl-2-(3-(N-methylsulfamoyl)phenyl)-1,2,3,4-tetrahydroquinoline-6-carboxylic acid as a white solid. Yield: 78.5%.MS (ESI+APCI) M+1=375.2.
