These common heterocyclic compound, 38487-86-4, name is 2-Amino-4-chlorobenzonitrile, its 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. 38487-86-4
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.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 38487-86-4.
