실험 절차

To a solution of 2-(4-aminophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid (50 mg, 0.17 mmol) in 5 mL of pyridine was added 2-fluorobenzene-1-sulfonyl chloride (41 mg 0.21 mmol) below 0° C. The mixture was stirred at room temperature under nitrogen overnight. Pyridine was removed in vacuo and the residue was purified by preparative thin layer chromatography to afford 2-(4-(2-fluorophenylsulfonamido)phenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylic acid as a yellow solid, 43 mg, yield: 62%. MS (ESI+APCI) M+1=455.50.
