Procedure
2.0 mL of trifluoroacetic acid was added to the obtained tert-butyl 2-(benzylsulfonamido)-4-phenethylbenzoate and stirred at room temperature for 1 hour. The solvent was evaporated under reduced pressure and the obtained residue was purified with reversed-phase silica gel column chromatography [eluent; 65-100% acetonitrile/0.1% trifluoroacetic acid aqueous solution] to obtain 5.1 mg of 2-(benzylsulfonamido)-4-phenethylbenzoic acid as white solid.
