Following the procedure of Example 121, but substituting 2-bromo-N,N-dimethylbutyramide for 2-bromo-N,N,2-trimethylpropionamide, and 4-methyl-3-phenylpyrazole for 3-phenylpyrazole, there were obtained the already described α-ethyl-N,N,4-trimethyl-3-phenylpyrazole-1-acetamide and N,N,β,4-tetramethyl-3-phenylpyrazole-1-propionamide having a boiling point of 170°/0.2 mm.
