Some common heterocyclic compound, 21667-62-9, name is 3-(3-Chlorophenyl)-3-oxopropanenitrile, molecular formula is C9H6ClNO, 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. name: 3-(3-Chlorophenyl)-3-oxopropanenitrile
EXAMPLE 41 Preparation OF 3- [5-AMINO-4- (3-CHLOROBENZOYL)-PYRAZOL-1-YL]-N-CYCLOPROPYL-4- methyl-benzamide A. 2- (3-Chlorobenzoyl)-3-phenylaminoacrylonitrile A solution of 3-chlorobenzoylacetonitrile (476 mg, 2.66 mmol, 1.0 eq) and diphenylformamidine (522 mg, 2.66 mmol, 1.0 eq) in 25 mL of toluene was stirred at room temperature for 2h then heated to 100 C overnight. The solution was cooled and diluted with hexanes. The resulting solid was filtered and dried to provide the desired product (566 mg, 75%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 21667-62-9, its application will become more common.
