Synthesis of 2-methyl-1,5-dinitro-3- and 2-methyl-1,3-dinitro-5-(trifluoromethyl)benzenes and their transformation into 6-nitro-4-(trifluoromethyl)- and 4-nitro-6-(trifluoromethyl)-1H-indoles

2-methyl-1,3-dinitro-5-(trifluoromethyl)benzenes is described. The first step is the nitration of otho- and para-methylbenzoic acids to furnish the corresponding dinitroacids. The dinitroacids then react with sulfur tetrafluoride to provide the corresponding trifluoromethylated products. The latter are easily transformed into 6-nitro-4-(trifluoromethyl)- and 4-nitro-6-(trifluoromethyl)-1H-indoles by applying
描述了2-甲基-1,5-二硝基-3-和2-甲基-1,3-二硝基-5-(三氟甲基)苯的容易的两步合成。第一步是将邻甲基苯甲酸和对甲基苯甲酸硝化,得到相应的二硝基酸。然后使二硝基酸与四氟化硫反应以提供相应的三氟甲基化产物。通过应用Batcho-Leimgruber合成规程,可将后者轻松转化为6-硝基-4-(三氟甲基)-和4-硝基-6-(三氟甲基)-1 H-吲哚。
