2-Chloro-1-fluoro-4-nitrobenzene (0.8 g, 4.56 mmol) and 2-(methyloxy)ethanol (0.52 g, 6.84 mmol) were combined and dissolved in Acetonitrile (15 mL). Potassium carbonate (2.4 g, 17 mmol) was then added and the resulting mixture was heated at 50° C. for 16 h. The reaction was not complete so additional potassium carbonate (1.0 g, 7.24 mmol) and 2-(methyloxy)ethanol (0.08 g, 1.05 mmol) were added as well as DMF (3 mL) to aid in solubilizing the reaction which was then heated at 85° C. for 16 h. The reaction was cooled to rt then diluted with EtOAc (250 mL) and water (150 mL). The organic layer was separated, washed with brine (100 mL), dried over Na2SO4, filtered and concentrated in vacuo to yield 1.0 g of the compound. 1H NMR (300 MHz, DMSO-d6): δ 8.31 (d, 1H), 8.21 (m, 1H), 7.38 (d, 1H), 4.35 (m, 2H), 3.72 (m, 2H), 3.32 (s, 3H).
