Notes:
Alkylation of 5-nitroindazole (I) with dimethyl sulphate and/or diethyl sulphate in presence of sodium hydroxide yields mixtures containing more 2-alkylated than 1-alkylated products. The action of diazomethane on 5-nitro (I) and 6-nitro-indazole (IV) was investigated. Reduction of nitroindazoles with hydrogen on Pd/charcoal proceeds smoothly. The synthesis of several new benzimidazole and indazole dye intermediates is also described.
