실험 절차
A solution of 4-ethyl-2-fluoro-benzonitrile (1.19 g, 8.0 mmol) in ether (70 mL) was cooled in an ice bath. To the cold, stirred solution was added LiAlH4 (600 mg, 16 mmol). The suspension was then heated to reflux. After several hours at reflux, the suspension was allowed to cool to ambient temperature and was quenched by the careful addition of H2O (600 μL), followed by 15% aqueous NaOH (600 μL), and finally H2O (1.8 mL). The resulting suspension was filtered, and the solids were washed thoroughly with ether. The filtrate was concentrated under reduced pressure to afford 4-ethyl-2-fluoro-benzylamine (1.16 g, 95% yield) as a liquid. This material was used for the subsequent amide formation without further purification. 1H-NMR (400 MHz, CDCl3): δ 7.21 (1H, app t, J=7.6 Hz), 6.96-6.86 (2H, m), 3.85 (2H, s), 2.63 (2H, q, J=7.6 Hz), 1.22 (3H, t, J=7.6 Hz).
