| titleOfInvention | Synthesis method of diarylurea compounds |
| abstract | The invention discloses a synthesis method of diarylurea compounds. The synthesis method comprises the following steps: adding a phenylamine compound shown in a formula II and bis(trichloromethyl) carbonic ester into a reaction solvent and reacting for 1-2h at 0-5 DEG C; then, adding a ETS-10 molecular sieve based catalyst, heating to 70-100 DEG C to react, performing tracking detection by virtue of TLC till the reaction is complete; and performing posttreatment on reaction liquid to obtain a diarylurea compound shown in formula I. The synthesis method has the advantages that the raw material conversion rate is 100%, the yield is 95% or above, the product purity is high, the used catalyst is nontoxic and odorless and can be reused, and therefore cost is saved. (The formulas I and II are shown in the specification.). |
