Versuchsvorschrift

To a solution of 2-(4-aminophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid (100 mg, 0.34 mmol) in pyridine (5 mL) was added benzenesulfonyl chloride (0.05 mL, 0.38 mmol) via syringe with ice cooling. Upon completion of the addition, the resultant mixture was allowed to warm back to room temperature and stir for 24 h. LC-MS showed the reaction was complete. Pyridine was removed in vacuo and the residue was purified by preparative thin layer chromatography to afford 81 mg of 3,3-dimethyl-2-(4-(phenylsulfonamido)phenyl)-1,2,3,4-tetrahydroquinoline-6-carboxylic acid as a white solid. Yield: 65%; MS (ESI+APCI) M+1=437.54.
