Reaktionsschritte
Add borane-tetrahydrofuran complex (16.21 mL, 1 M) to a mixture of 2-fluoro-4-nitro-benzoic acid (1.2 g) and tetrahydrofuran (10 mL) at 0° C. Heat at 80° C. for 3 hours. Cool at room temperature and add 1 N aqueous hydrochloric acid (20 mL) and extract with ethyl acetate. Wash with saturated aqueous sodium bicarbonate and dry the remaining organic phase over sodium sulfate and concentrate under reduced pressure to provide (0.91 g, 83%) of an oil. Add (2-fluoro-4-nitro-phenyl)-methanol (0.91 g) to a mixture of dioxide manganese (1.1 g) in 20 ml of dichloromethane. Stir at room temperature overnight and filter over Celite®. Concentrate under reduced pressure to provide (0.27 g, 30%) of the title compound as an oil.
