Attempted Niementowski condensation of anthranilic acid and its ester with 3-Methyl-1-phenylpyrazolin-5-one

Two groups of compounds were formed in the attempted reaction of anthranilic acid and its ester with 3-methyl-1-phenylpyrazolin -5-one. The reactions of 3-methyl-1-phenylpyrazolin-5-one with aniline generated by decarboxylation of anthranilic acid constituted the first group of products. The second group of products comprised of pyrazole derivatives formed mainly by dimerization and dehydration of two molecules of 3-methyl-1-phenylpyrazolin-5-one.
