Reaction Steps
4,5-Difluoro-2-nitrophenol (INTERMEDIATE 51) (2.02 g, 11.54 mmol) and potassium carbonate (2.39 g, 17.3 mmol) were added into a 50 mL round-bottomed flask. DMF (10 mL) was added. Iodomethane (1.08 mL, 17.3 mmol) was added. The reaction mixture was stirred at RT overnight. The mixture was poured into water (60 mL) and stirred for 10 min. Filtration afforded the title product as a precipitate (1.9 g, 87% yield).
