36216-80-5, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Benzo[d]isoxazol-3-amine, cas is 36216-80-5,the Benzisoxazole compound, it is a common compound, a new synthetic route is introduced below.
Phenyl 1 ,2-benzisoxazol-3-ylcarbamateA solution of 1 ,2-benzisoxazol-3-amine (1.00 g; CASNo. 36216-80-5) and triethylamine (1.09 ml_) in acetonitrile (5 ml_) was added dropwise to at 0 0C solution of phenyl chloroformate (0.989 ml_) in THF (20 ml_). The reaction was stirred at 0 0C for 1 h and then allowed to warm to RT overnight. The reaction was diluted with ethyl acetate and washed with 1 N HCI and brine. The organic layer was dried over sodium sulfate, filtered, and concentrated to give the crude product as a reddish brown solid. The solid was triturated with refluxing diisopropyl ether, cooled to RT, and filtered to give final product as a tan solid (1.22 g, 64%). m/z 255 (MH+).
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.
