Versuchsvorschrift
A mixture of 10.4 parts of (4-amino-3-nitrophenyl) (2-fluorophenyl)methanone, 14.03 parts of methylhydrazine and 79 parts of ethanol was stirred for 40 hours at reflux temperature. After cooling, the precipitated product was filtered off, washed with 2,2'-oxybispropane and dried, yielding 5.5 parts (51.3%) of 4-(1-methyl-1H-indazol-3-yl)-2-nitrobenzenamine; mp. 230.6° C. (interm. 7). In a similar manner there was also prepared: 4-(1H-indazol-3-yl)-2-nitrobenzenamine (interm. 8).
