Reaction Steps
By a method analogous to that described in Example 28, 1-phenyl-3-(p-methoxyphenyl)-1,3-propanedione was reacted with bromoacetic acid-ethyl ester to form 3-benzoyl-3-p-anisoyl-propionic acid-ethyl ester, which was further reacted with phenylhydrazine to form 1,3-diphenyl-5-(p-methoxyphenyl)-pyrazol-4-acetic acid-ethyl ester, from which was obtained by saponification 1,3-diphenyl-5-(p-methoxyphenyl)-pyrazol-4-acetic acid having a melting point of 160°-163° C.
