Abstract
Two groups of compounds were formed in the attempted reaction of anthr anilic acid and its eater with 3-methyl-1-phenylpyrazolin-5-one. The r eactions of 3-methyl-1-phenylpyrazolin-5-one with aniline generated by decarboxylation of anthranilic acid constituted the first group of pr oducts. The second group of products comprised of pyrazole derivatives formed mainly by dimerization and dehydration of two molecules of 3-m ethyl-1-phenylpyrazolin-5-one.
