A mild and simple method for the synthesis of 3-indolyl-substituted phthalides via Friedel-Crafts reaction of indoles with 2-formylbenzoic acids catalyzed by an acidic cation exchange resin Amberlyst 15 has been developed. The reaction affords a wide range of 3-indolyl-substituted phthalides in high yield. The structures of the corresponding products were confirmed on the basis of 1H NMR, 13C NMR, IR and HRMS spectra.
