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.

摘要:The process of the present invention creates a sustainable and closed water loop allowing inherent recycles of all liquid streams generated in the process. The liquid streams generated during the process of the invention are inherently recycled completely, making the process of the present invention a zero liquid discharge process which is environmentally friendly and sustainable. This invention further relates to a sustainable chemical process of reduction of R—NO 2 or R—NO into corresponding R—NH 2 that produces environmentally friendly R—NH 2 in good yields and selectivity with large of mother liquor recycle. The process has a wide scope in that it can be applied to a number of molecules.
