摘要:Disclosed is a process for the synthesis of chlorzoxazone (1) from 4-chloro-2-aminophenol and ethyl chloroformate in the presence of a base. n n n n n n n n n n The process is particularly advantageous because it uses ethyl chloroformate instead of triphosgene, a highly dangerous reagent that releases phosgene and must be handled with extremely strict procedures to guarantee the safety of operators in industrial facilities. n Ethyl chloroformate allows the possibility of working with a number of solvents, including water. n The yield and purity of the product obtained are very high.
