Water → 1-(phenylsulfonyl)-1H-indole-3-carboxylic acid

Participants

Reaction Steps

4.8 mg of indole-3-carboxylic acid was dissolved in 1 mL of tetrahydrofuran, 0.042 mL of n-butyllithium (1.58 M hexane solution) was added to the solution at 0° C., the resulting mixture was stirred for 30 minutes. Then 5.3 mg of benzenesulfonyl chloride was added to the mixture, and the resulting mixture was stirred at 0° C. overnight. Water and chloroform were added to the mixture, the organic layer was separated and concentrated under reduced pressure, and the residue was purified by HPLC to obtain 1.0 mg of 1-(phenylsulfonyl)-1H-indole-3-carboxylic acid.
