with dimethylamine p-toluenesulfonate for 10 h;Heating;
Steps:
4
4. Add CF3SOCl to the appropriate reagent, react, heat up, and then add 99.5% of 5-amino-3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)pyrazole. And a mixture of p-toluenesulfonic acid dimethylamine salt, while adding a catalyst, and reacting for 10 hours, the solvent was evaporated under reduced pressure to obtain 98-99% of fipronil.
