Method for preparing 6-(2-fluoroethoxy)-2-methylbenzoxazole |
| abstract |
Disclosed is a method for preparing 6-(2-fluoroethoxy)-2-methylbenzoxazole. 2-methylbenzoxazole-6-alcohol and 1-bromine-2-fluoroethane serve as raw materials, N, N-dimethylformamide serves as a solvent, and the 2-methylbenzoxazole-6-alcohol reacts with the1-bromine-2-fluoroethane to produce the 6-(2-fluoroethoxy)-2-methylbenzoxazole in the presence of cesium carbonate. The problems that the environment is polluted, the operation is poor and the product purity is low caused by the fact that triphenylphosphine is used in the prior art are solved. The method is conducted on the mild reaction condition and is suitable to industrial production. The invention also provides a method for purifying recrystal. The method has the advantages of being simple in operation and high in purity. |
