A mixture of methyl 2-(3-(cyclopropanecarboxamido)-4-fluorophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (0.26 mmol, 1.0 eq) and 4.5 mL sodium hydroxide (1 mol/L) in 3 mL methanol was stirred at reflux for 1-2 h. LC-MS indicated that the starting material was consumed completely. The methanol was removed by reduced pressure. The residue was acidified pH to 5-6 with 1 M hydrochloric acid. A lot of precipitates were formed and collected by filtration to afford 71 mg of 2-(3-(cyclopropanecarboxamido)-4-fluorophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid as a white solid; yield: 72%. MS (ESI+APCI) M+1=383.
