Procedure

4-Nitrophenol (2.0 g, 14.4 mmol) was dissolved in DMF (50 mL) and potassium carbonate (6.0 g, 43 mmol) and bromomethylcyclopropane (1.51 mL, 16 mmol) were added and the resulting mixture was stirred at room temperature for 16 hours. The mixture was diluted with ethyl acetate (50 mL) and washed with a saturated aqueous solution of sodium chloride (2×50 mL). Drying (MgSO4) and concentration afforded 2.23 g (75%) of 1-cyclopropylmethoxy-4-nitrobenzene as an oil.
