A kind of technology for preparing 4-bromo N-arylpyrazole compounds |
| abstract |
This scheme discloses a process for preparing 4-bromo N-arylpyrazole compounds: in organic solvent dimethyl sulfoxide (DMSO), N-aryl-3-pyrazolidone compounds are used as raw materials , and react with N-bromosuccinimide (NBS) under the heating conditions of air and 95-105 DEG C to obtain 4-bromo-N-arylpyrazole compounds. |
