59-49-4, 2-Benzoxazolinone is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 3,Add 1.5 eq of TCCA to the suspension of dichloroethane containing the 2-benzoxazolone obtained in Step 1,Stir at room temperature for 10 min, after extraction,After rotary evaporation, 6-chlorobenzoxazolone was obtained.The yield is over 90%, no catalyst is needed, no by-products,The reaction rate is fast and there is no requirement for temperature.The method of step 3 is simple to operate,Low equipment requirements, no harm to the environment, suitable for large-scale production.
As the paragraph descriping shows that 59-49-4 is playing an increasingly important role.
