5-氯-1,3-二甲基-N-苯基吡唑-4-甲酰胺 | 5-chloro-1,3-dimethyl-N-phenylpyrazole-4-carboxamide | 64174-45-4 | C12H12ClN3O | 249.7 |
Methods are described for the synthesis of 1,3-dimethyl-N-phenylpyrazole-4-carboxamid (3) and the isomeric 1,5-dimethyl compound (4), structural analogues of the systemic fungicide carboxin. Evidence confirming the structural assignment of the compounds is presented, and a convenient method for the removal of the amino group from some aminopyrazoles is described.
