New downstream synthetic route of Benzo[d]isoxazol-3-amine

The chemical industry reduces the impact on the environment during synthesis, 36216-80-5,Benzo[d]isoxazol-3-amine,I believe this compound will play a more active role in future production and life.

36216-80-5,A common heterocyclic compound, 36216-80-5,Benzo[d]isoxazol-3-amine, 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.

To prepare a-5, a-4 (2.1 g, 0.015 mol) was added to chlorosulfonic acid (4.1 ml, 0.060 mol) at room temperature (RT). Said reaction mixture was stirred overnight under an inert atmosphere such as nitrogen at 60C. The mixture was then poured in ice/water. The precipitate was filtered and dried with toluene in a Buchi-apparatus (2.1 g, yield 60%).

The chemical industry reduces the impact on the environment during synthesis, 36216-80-5,Benzo[d]isoxazol-3-amine,I believe this compound will play a more active role in future production and life.
