Reaktionsschritte

To a solution of 2-fluoro-5-(trifluoromethyl)benzonitrile (8.0 g, 42.3 mmol, Aldrich) in tetrahydrofuran (50 mL) were added sodium hydride (1.9 g, 46.5 mmol, 60% in mineral oil) and (S)-1-methylpyrrolidin-3-ol (4.7 mL, 46.5 mmol, Aldrich). After stirring at room temperature for 3 hours, the reaction mixture was quenched with saturated NaHCO3 (30 mL). The aqueous layer was extracted with ethyl acetate (3×30 mL). The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to afford 10.9 g of the title compound. MS (ESI+) m/z 271 (M+H)+.
