Procedure
1.0 mL of trifluoroacetic acid was added to 1.0 mL of methylene chloride solution containing 20 mg of tert-butyl 4-phenethyl-2-(6-(1H-pyrrol-1-yl)pyridine-3-carboxamido)benzoate and stirred at room temperature for 1 hour and 30 minutes. Tine solvent was evaporated under reduced pressure and diisopropyl ether was added to the obtained residue and a solid substance was separated by filtration to obtain 17 mg of 4-phenethyl-2-(6-(1H-pyrrol-1-yl)pyridine-3-carboxamido)benzoic acid as white solid.
