A synthetic method of methyl-4-(trifluoromethoxy) phenyl
carbamate. Raw materials of 4-trifluoromethoxy-
aniline,
methyl chloroformate and alkalis and a mixed
solvent of water and organic solvents are mixed and undergo directly a reaction to produce a product of methyl-4-(trifluoromethoxy) phenyl
carbamate. The synthetic method comprises the following steps of 1, adding 4-trifluoromethoxy-
aniline,
sodium hydroxide,
tetrahydrofuran and water into a container, mixing well and make the mixture undergo a reaction at a temperature of 0 to 5 DEG C for 2 hours, 2, heating the reaction products to
room temperature and stirring for 30 minutes, adding slowly
methyl chloroformate into the heated reaction products and stirring at
room temperature for 6 to 7 hours, 3, cooling the reaction products obtained from the step 2 to 0 DEG C and stirring for 30 minutes, and 4, carrying out a suction
filtration process for the reaction products obtained from the step 3 to collect solids, and washing and
drying the solids to obtain desired products. The synthetic method has the advantages that the synthetic method is simple and practical, has a high efficiency and can realize an end product yield more than 95%; reagents adopted in synthesizing processes have the advantages of
low toxicity, high economic efficiency, less side effects, less
corrosion on equipment and less
pollution on environment; and prices of raw materials are cheap thus a production cost is low and the synthetic method has a high economic efficiency and good application prospects.
