Versuchsvorschrift
Add 5N sodium hydroxide (1.17 ml, 3 eq) to a solution of 4-(3-Cyclohexyl-indole-1-sulfonyl)-benzoic acid methyl ester (775 mg, 1.95 mmol, 1 eq) dissolve in a mixture of 10 ml THF and 5 ml MeOH. Stir for 1.5 hours. Remove solvent on rotovap and add 1 N HCl. Dissolve the solid that crashes out of solution in EtOAc. Extract product into organics, separate organics, dry over MgSO4, and concentrate on rotovap to give 4-(3-Cyclohexyl-indole-1-sulfonyl)-benzoic acid (646 mg, 86% yield) as a white solid.
