反応手順
15.7 Grams (0.1 mole) of 1-methyl-2-hydroxymethyl-5-nitro-imidazole and 21.0 g (0.1 mole) of 2-nitro-4-trifluoromethylfluoro-benzene dissolved in 100 ml of butanone-2 were mixed with 15 g of triethylamine and were heated for 2 hours on a steam bath. The crystals obtained when the solution had been cooled were suction-filtered, were washed with water and were recrystallized from a little isopropanol, while adding charcoal. As a result, 25 g (= 72% of the theory) of 1-methyl-2-(4-trifluoromethyl-2-nitrophenoxymethyl)-5-nitro-imidazole were obtained in the form of yellowish crystals having a melting point of 126° C.
