実験手順

Step M (4): Sodium hydride (120 mg, 5 mmol) was added to a solution of 2,3-difluoro-5-nitrophenol (250 mg, 1.4 mmol) in DMF/THF (4 mL/4 mL). After 10 min, iodomethane (0.2 mL, 5 mmol) was added. The mixture was heated at 80° C. for 2 h. The reaction mixture was quenched with 1 N HCl. The mixture was diluted with water and extracted with EtOAc. The organic layer was washed with brine, dried over sodium sulfate, filtered, and concentrated in vacuo to afford 1,2-difluoro-3-methoxy-5-nitrobenzene (130 mg, 48% yield).
