ABSTRACT:
3-Aminoindazoles bearing a carbo(lower alkoxy), lower alkylamide or di(lower alkyl)amide group in the 1-or 2-position and further being optionally substituted in one or more of the 4-, 5-, 6- and/or 7-positions are analgesic, anti-inflammatory and antipyretic agents. The compounds, of which 3-amino-6-chloroindazole-1-carboxylic acid ethyl ester is a typical embodiment, are prepared through treatment of the appropriate 3-aminoindazole with a derivative of carbonic acid or through thermal isomerization.
