Reaction Steps
1-Bromo-4-(bromomethyl)-3-methylbenzene (13.2 g, 50.1 mmol) is dissolved in DMF (65 mL). The reaction mixture is cooled to 0-5° C. and NaCN (3.66 g, 74.6 mmol) is added follow by water (8 mL). The reaction is stirred overnight at room temperature and water (170 mL) is added followed by NaHCO3 sat. (130 mL) and hexane/Et2O (2:1) (150 mL). The organic phase is separated and the aqueous phase extracted with hexane/Et2O (2:1) (3×150 mL). The combined organic phases are washed with water (170 mL), dried over MgSO4, filtered and concentrated under reduced pressure to provide the expected product 2-(4-bromo-2-methylphenyl)acetonitrile (9.76 g, 93%) as an orange oil. 1H NMR (300 MHz, CHLOROFORM-D): δ 7.40-7.32 (2H, m), 7.23 (2H, d, J=8.2 Hz), 3.61 (2H, s), 2.32 (3H, s).
