Sodium Methoxide → HCID 59007107、化合物

4-Bromo-1-(bromomethyl)-2-nitrobenzene (Heterocycles 1994, 39, 767) (8.3 g, 28 mmol) was dissolved in methanol (75 ml) at 0° C. 30% Sodium methoxide in methanol solution (10.7 ml, 56 mmol) was added dropwise and the solution stirred at room temperature for 4 hours. The mixture was concentrated to a small volume and partitioned between ethyl acetate and saturated aqueous sodium hydrogen carbonate solution. The organic layer was separated and then washed with saturated aqueous sodium bicarbonate solution, water (×3), brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by chromatography on silica gel (hexane to ethyl acetate) to afford the title compound (D16). MS (ES+) m/e 246/248 [M+H]+.
