Hydrochloric Acid → 3-{[5-(Methoxycarbonyl)pyridin-2-yl](propyl)sulfamoyl}benzoic acid

Participants

Reaction Steps

To a mixture of 175 mg of methyl 6-{propyl[(3-{[2-(trimethylsilyl)ethoxy]carbonyl}phenyl)sulfonyl]amino}nicotinate and 5 mL of THF was added dropwise a solution of TBAF in THF (1 M, 0.750 mL), followed by stirring at room temperature for 4 hours. To the reaction mixture was added 0.1 M hydrochloric acid, followed by extraction with ethyl acetate. The organic layer was washed with saturated brine, and then dried over magnesium sulfate. The solvent was evaporated under reduced pressure and then dried under reduced pressure to obtain 110 mg of 3-{[5-(methoxycarbonyl)pyridin-2-yl](propyl)sulfamoyl}benzoic acid as a colorless powder.
