Reaktionsschritte

To a solution of (3-bromo-5-nitrophenyl)methanol (500 mg, 2.155 mmol) in DMF (7.2 mL) was added iodomethane (0.40 mL, 6.46 mmol. The solution was cooled to 0° C. before NaH (60% dispersion in mineral oil, 172 mg, 4.31 mmol) was added. The reaction was stirred at 0° C. and allowed to come to room temperature. After 2 hours the reaction was quenched with water and ethyl acetate was then added. Extraction was done with ethyl acetate (3×). The combined organic layer was dried over magnesium sulfate and then filtered. Ethyl acetate was then removed in vacuo to afford 1-bromo-3-(methoxymethyl)-5-nitrobenzene (470 mg, 1.910 mmol, 89% yield) as a yellow solid. 1H NMR (500 MHz, DMSO-d6) δ 8.25 (s, 1H), 8.13 (s, 1H), 7.96 (s, 1H), 4.53 (s, 2H), 3.33 (s, 3H).
