Методика

105 g of 2,4-dinitro-6-methylanisole, 1.35 l of ethanol, 150 ml of water and 1 g of Pd/C (5% strength) were initially introduced into the autoclave and hydrogenated at 50° C. with a hydrogen pressure of 50 bar for 12 h. Subsequently, the mixture was cooled and then poured into 1.0 l of semiconcentrated HCl. The catalyst was filtered off, and the filtrate was evaporated to dryness on a rotary evaporator. The residue was extracted by boiling with 2×150 ml of ethanol, filtered off and dried overnight under reduced pressure.
