Reaction Conditions

Reaction Steps

Sodium hydride, 60% suspension in oil (3.6 g, 0.09 mol), is added to a solution of cyclopropylmethanol (6.49 g, 0.09 mol) in dry DMF (200 ml) at 0° C. under nitrogen. After 30 min at 0° C., 5-bromo-2-fluorobenzonitrile (12.0 g, 0.06 mol) in dry DMF (50 ml) is added, and the reaction is stirred at 50° C. for 16 h. Ice-water (200 ml) is added to the reaction mixture, which is then extracted with ethyl acetate (2×200 ml). The organic phases are washed with water (2×200 ml) and saturated sodium chloride solution (1×200 ml) and dried over sodium sulfate. After removal of the solvent, the crude product is purified by chromatography, giving 14 g of a yellow oil;
