Reaction Steps

This compound was prepared in a manner similar to that described for 3-bromo-5-fluorobenzonitrile from commercially available 2,6-dibromotoluene (1.80 g, 7.20 mmol), DMF (11 mL), pyridine (1.1 mL), and copper (I) cyanide (0.52 g, 5.76 mmol). The crude product was purified by flash column chromatography (100 mL silica, hexane) to afford 50 mg (35%) of 3-bromo-2-methylbenzonitrile. Data for 3-bromo-2-methylbenzonitrile: 1H NMR (400 MHz, acetone-d6) 7.88 (d, J=8.0, 1H), 7.73 (d, J=8.0, 1H), 7.32 (t, J=15.8, 7.9, 1H), 2.58 (s, 3H).
