Procedure

5-Fluoro-2-nitrophenol (6 g, 38.2 mmol) was dissolved in anhydrous DMF (20 ml). Potassium carbonate (5.3 g, 38.2 mmol) was added, followed by iodomethane (2.28 ml, 38.2 mmol). The reaction was stirred at room temperature for 16 h, then partitioned between dichloromethane and water. The organic layer was washed three times with 1M sodium hydroxide and once with brine, then dried over sodium sulfate. Removal of the solvent in vacuo afforded the title compound as a yellow oil, which solidified upon standing.
