| titleOfInvention | Method for preparing oxazole compound |
| abstract | The invention relates to a method for preparing oxazole compound, in organic solvent and organic alkali (especially triethylamine), add the assistant as formula (I) or (II) or formula (III), drip organic solution of phosgene or diphosgene or triphosgene and compound (IV) to carry on the cyclization reaction, can get product (V) with high yield, can inhibit the production of the by-product greatly at the same time. The reaction conditions are mild, and compared with the method without adding an auxiliary agent, the technical scheme of the invention can improve the yield of the product (V) to more than 95 percent and reduce the by-product by more than 10 percent. |
