HCID 20370480N,N-Dimethyl-2-(4-methyl-3-phenyl-1H-pyrazol-1-yl)-2-phenylacetamide

Procedure

Following the procedure of Example 68, but substituting 4-methyl-α,3-diphenylpyrazole-1-acetic acid for α,4-dimethyl-3-phenylpyrazole-1-acetic acid and dimethylamine for aqueous ammonia, there was obtained N,N,4-trimethyl-α,3-diphenylpyrazole-1-acetamide having a melting point of 135.5°-138° C.
