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.36216-80-5,Benzo[d]isoxazol-3-amine, 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+).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 36216-80-5, other downstream synthetic routes, hurry up and to see.
