A common heterocyclic compound, 719-64-2,5-Chloro-3-phenylbenzo[c]isoxazole, 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. 719-64-2
(3) Mix tetrahydrofuran and triethylamine,Then add 5-chloro-3-phenyl-2,1 benzisoxazole,Palladium carbon catalyst mixing,Passing nitrogen,Replace the air 8 times,Then pass hydrogen to a pressure of 0.1 MPa.Magnetic stirring for 1h,Then filter,The obtained filter residue was vacuum dried at 50 C for 4 h.among them,Tetrahydrofuran,Triethylamine,5-chloro-3-phenyl-2,1 benzisoxazole,The mass ratio of the palladium carbon catalyst is 30:5:2:0.08,That is, 2-amino-5-chlorobenzophenone is obtained.
This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,5-Chloro-3-phenylbenzo[c]isoxazole,719-64-2,its application will become more common.
