Reaction Steps

Following the procedure of Example 121, but substituting 2,3-dibromo-N,N-dimethylpropionamide for 2-bromo-N,N,2-trimethylpropionamide and 4-methyl-3-phenylpyrazole for 3-phenylpyrazole there was obtained α-bromo-N,N,4-trimethyl-3-phenylpyrazole-1-propionamide having a melting point of 104°-107° C.
