Alkylation of 1-Alkyl-3-methyl-1,4-dihydropyrazolo[4,3-c]pyrazoles with Halocarboxylic Acids Esters

详细

A preparative method for the synthesis of 1-alkyl-3-methyl-1,4-dihydropyrazolo[4,3-c]pyrazoles was developed. The alkylation of the obtained compounds with halocarboxylic acid esters was also investigated. A principal possibility of creating libraries of compounds based on pyrazolo[4,3-c]pyrazole derivatives was shown.
