Versuchsvorschrift
KCN (154 mg, 2.36 mmol) was added to a solution of 5-(bromomethyl)-2-phenylthiazole (400 mg, 1.57 mmol) in dry DMF (10 mL). The resulting reaction mixture was stirred at room temperature for 10 h. The mixture was then quenched with water and the organic product was extracted with EtOAc. The combined extracts were washed with H2O and brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The crude product was purified by column chromatography (silica gel 60-120 mesh, eluent 20% EtOAc in petroleum ether) to afford 2-(2-phenylthiazol-5-yl)acetonitrile (230 mg, yield 73%) as a white solid. 1H NMR (300 MHz, CDCl3) δ 7.94-7.90 (m, 2H), 7.76 (s, 1H), 7.47-7.45 (m, 3H), 3.98 (d, J=1.1 Hz, 2H). MS (ESI) m/z: Calculated for C11H8N2S: 200.05. found: 201.2 (M+H)+.
