20%; 74% | General procedure: n-Butyllithium (1.67 M solution in hexane, 3.3 mL, 5.5 mmol) was added dropwise to a solution of p-bromotoluene (855 mg, 5.0 mmol) in THF (5 mL) at -70 C. After 30 min, the resulting mixture was warmed and stirred for 5 min at 0 C. Then, DMF (0.43 mL, 5.5 mmol) was added and the obtained mixture was stirred at 0 C. After 1 h at the same temperature, aq NH3 (10 mL, 150 mmol) and I2 (1.40 g, 5.5 mmol) were added and the obtained mixture was stirred for 2 h at rt. The reaction mixture was quenched with satd aq Na2SO3 (15 mL) and extracted with Et2O (3×20 mL). The organic layer was washed with brine and dried over Na2SO4 to provide 4-methylbenzonitrile in over 80% purity. The product was purified by a short column chromatography on silica gel (Hexane/EtOAc=9:1) to give pure 4-methylbenzonitrile in 80% yield as a colorless solid. |
