With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.651780-27-7,Ethyl 6-bromobenzo[d]isoxazole-3-carboxylate,as a common compound, the synthetic route is as follows.
A solution of ethyl 6-brom-1, 2-benzisoxazole-3-carboxylate (Intermediate 55) (0.05g) and cyclopropylamine (0. 03ml) in methanol (lml) was stirred at reflux for 6h. The solvent was evaporated and the residue was triturated with ether to give the title compound as a white solid (0.04g).
As the paragraph descriping shows that 651780-27-7 is playing an increasingly important role.
