反応手順
The nitrophenol starting material B2 (3.1 g; 14.2 mmol) was dissolved in DMF (20 mL) and to the solution was added ground cesium carbonate (5.58 g; 17.1 mmol) followed by MeI (2.6 mL; 42.5 mmol). The mixture was stirred at room temperature overnight. The DMF was evaporated, the residue taken up in ether (1×200 mL), washed with water (1×200 mL), brine (4×100 mL), dried (MgSO4), filtered and evaporated to afford the crude 2-bromo-3-nitroanisole B3 (94%; 3.1 g) as an orange solid.
