実験手順

2-Bromo-6-nitrophenol (5.1 g, 23.4 mmol) was dissolved in DMF (60 mL), then 95% NaH (900 mg, 35.6 mmol) was added in a few portions, followed by the addition of iodomethane (3.0 mL, 6.8 g, 48.5 mmol). The reaction was stirred at room temperature overnight, then heated at 50° C. for 3 hours. The reaction was cooled, poured into water, and the solids filtered off and dried. The product (5.5 g, 100%) was recovered as tan solids. 1H NMR (300 MHz, DMSO-d6) δ 8.02 (dd, J=8.1, 1.7 Hz, 1H), 7.96 (dd, J=8.1, 1.7 Hz, 1H), 7.83 (dd, 8.1, 8.1 Hz, 1H), 3.92 (s, 3H).
