Six novel 4-aminoantipyrine derivatives as potential nonsteroidal antiinflammatory and analgesic compounds were prepared and their antiinflammatory-analgesic activity were compared with antiprine. Succinyl chloride and Ac $_2$O were reacted with glycine, respectively, to give glycine compounds (3-4, 9-10), which were treated with hydroxysuccinimide and dicyclohexyl carbodiimide to yield active esters (5-6, 11-12), and then reacted with 4-aminoantipyrine to prepare 4-aminoantipyrine derivatives (7-8, 13-14). 4-Aminoantipyrine reacted with succinyl chloride and Ac $_2$O, respectively, to give succinyl bis aminoantipyrine (15) and acetyl aminoantipyrine (16). Compounds (7), (8) and (13) gave comparable antiinflammatory activity to antipyrine.
