Sodium hydride → 2-Cyclopropylmethoxy-4-fluoro-1-nitrobenzene

関与物質

反応手順

Cyclopropyl methanol (15 g, 207 mmol) was added to a stirred suspension of NaH (60% in mineral oil, 8.37 g) in 200 mL THF over a period of 15 min at 0° C. under an atmosphere of nitrogen. The reaction mixture was allowed to warm to room temperature and stirred for 1 h at RT. The mixture was cooled to 0° C. and a solution of 2,4-difluoro-1-nitrobenzene (30 g, 187 mmol) in 200 mL THF was added in a drop wise manner. The reaction mixture was stirred at 0° C. for 2 h and then poured onto ice water. The mixture was extracted with ethyl acetate (3×100 mL). The combined organic layers were dried over MgSO4 and concentrated under reduced pressure to give 22.0 g of 2-(cyclopropylmethoxy)-4-fluoro-1-nitrobenzene as an orange oil (86%).
