Participants

Reaction Steps

To a stirred solution of methyl 2-(2-(3-fluorophenylsulfonamido)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (1.99 g, 4.2 mmol, 1.0 eq.) in tetrahydrofuran/methanol (25 mL/25 mL) was added sodium hydroxide (24 mL, 22.63 mmol, 5.4 eq.). The mixture was heated to reflux and stirred for 5 h. LC-MS indicated that 2005467-032-01 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. The precipitation was filtered, washed with water and dried to give 1.357 g of 2-(2-(3-fluorophenylsulfonamido)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid as off-white solid. yield: 92.7% (for two steps). MS (ESI+APCI) M+1=455.2.
