Procedure

A mixture of methyl 2-(2-(4-fluorophenylsulfonamido)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (66 mg, 0.14 mmol, 1.0 eq.) and 1.4 mL aqueous solution of sodium hydroxide (2 M, 2.8 mmol, 20 eq.) in tetrahydrofuran (4 mL) was stirred at reflux for 3 h. Thin layer chromatography indicated that the starting material was consumed completely. The tetrahydrofuran was removed under reduced pressure and the residue was acidified to pH 5-6 with 1 M hydrochloric acid. Then a lot of white precipitates were formed and collected by filtration to afford 48 mg of 2-(2-(4-fluorophenylsulfonamido)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid as a white solid; yield: 76%. MS (ESI+APCI) M+1=455.
