실험 절차

To tert-butyl 6-(2,5-difluorophenyl)nicotinate in DCM (12 mL) at 0° C. was added TFA (5 mL). After stirring at room temperature overnight, toluene was added (10 mL) and the solvent removed to give a white solid (176 mg, 97%), 6-(2,5-difluorophenyl)nicotinic acid. LC/MS (M+H)=236.0 observed, 236.05 expected
