Versuchsvorschrift

1.8 g. of 4,7-dinitro-5,6-dimethylindazole, prepared in accordance with the procedure of E. Nelting, Ber. 37, 2556 (1904), were hydrogenated at room temperature in 50 ml. of ethanol and 5 ml. of concentrated hydrochloric acid in the presence of 0.1 g. of catalyst (10% Pd on carbon). After the absorption of H2 ceased, the product was filtered off from the catalyst and reduced. Brown crystals were obtained. Analysis:
