876-31-3, A common compound: 876-31-3, name is 4-(Cyanomethyl)benzonitrile, belongs to nitriles-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
General procedure: Benzonitrile 1a (103 mg, 1.0 mmol) and WEPPA (2.0 mL) were added into a 10-mL closed tubewith a stir bar. Then the reaction was stirred in a closed vessel synthesis reactor at 150 C for 0.5 h.After cooling to ambient temperature, the resulting precipitate was collected by filtration, washed withice water, and further dried in a vacuum drying oven. The filtrate was evaporated under reducedpressure. The resultant residue was purified by silica gel column chromatography (eluent: petroleumether (35-60 C)/EtOAc = 2:1 to 0:1, v/v). Finally, these two parts were combined to produce the desiredbenzamide 2a with a 94% yield.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-(Cyanomethyl)benzonitrile, other downstream synthetic routes, hurry up and to see.
