Reference of 22364-68-7,Some common heterocyclic compound, 22364-68-7, name is 2-(o-Tolyl)acetonitrile, molecular formula is C9H9N, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: Benzonitrile (103 mg, 1 mmol) and sodium azide (97.5 mg, 1.5 mmol) were dissolved in 2 ml of dry DMF in a 25 ml round bottom flask. PbCl2 (27.8 mg, 0.1 mmol, 10 mol %) was added to the reaction mixture and stirred at 120 C for 8 h under nitrogen. After completion of the reaction (as monitored by TLC), the reaction mixture was cooled to room temperature and 10 ml of ice water was added followed by addition of 3 N HCl until the reaction mixture became strongly acidic (pH 2-3). The reaction mixture was extracted three times with 20 ml ethyl acetate. The organic layer was washed with brine solution and dried over anhydrous sodium sulfate, and was evaporated under reduced pressure to give a white solid product of 5-phenyl 1H-tetrazole with 81% yield.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-(o-Tolyl)acetonitrile, its application will become more common.
