Reaction Steps

Sodium hydride (60% dispersion in mineral oil; 2.9 g, 71.8 mmol) was slowly added to a solution of (2,3-difluorophenyl)acetonitrile (10.0 g, 65.3 mmol) and ethyl 4-bromobutanoate (12.7 g, 65.3 mmol) in N,N-dimethylformamide (100 mL) at 0° C. After 30 min, the reaction mixture was warmed to ambient temperature. After 3 h, water was added and the mixture was extracted with ethyl acetate (2×). The organic extracts were washed with saturated aqueous ammonium chloride, saturated brine, dried over magnesium sulfate, filtered and concentrated to give the title compound. MS 267.1 (M+1).
