Procedure

Sodium hydride (50% in oil; 1.63 g) was cautiously added to a solution of cyclobutanol (2.7 g) in DMF (12 ml). After gas evolution ceased, 4-bromo-1-bromomethyl-2-fluorobenzene (10 g) was added at 0° C. After 6 hours at room temperature, the mixture was cautiously hydrolyzed and then partitioned between water and ethyl acetate. The organic phase was dried over magnesium sulfate and concentrated. 4-Bromo-1-cyclobutoxymethyl-2-fluorobenzene was obtained as crude product in this way.
