실험 절차

2,6-difluoro-3-methoxybenzonitrile (4.42 g, 26.1 mmol) was dissolved in DCM (10 mL) at 0° C. then 1 M BBr3 (52.2 mL, 52.2 mmol) was added. The reaction mixture was then warmed up to RT and stirred overnight. The reaction mixture was poured into ice water and extracted with more DCM. The organic layer was separated, dried over Na2SO4, filtered, and evaporated to dryness to yield 2,6-difluoro-3-hydroxybenzonitrile: LC-MS: M+1=156.
