Abstract

A series of 1-methyl-4-arylaminopyrazole-3- and -5-carboxylic acids were synthesized by the reaction of 1-methyl-4-halopyrazole-3- and -5-carboxylic acids with aromatic amines in the presence of a copper catalyst; treatment with phosphorus oxychloride converted them to the corresponding 9-chlorosubstituted 1-methyl-1H- and 2-methyl-2H-pyrazolo[4,3-b]quinolines.
