실험 절차

To 5 ml. of cold 90% sulfuric acid was added 1 g. (0.004 mole) of 1-methyl-5-nitro-2-[2-(3-cyanophenyl)vinyl]imidazole, and the resulting solution was warmed on a steam bath for five minutes and then poured into ice water. The solid which separated was collected by filtration, washed with water, dried and recrystallized from ethanol to give 1-methyl-5-nitro-2-[2-(3-carbamylphenyl)vinyl]imidazole, m.p. 254°-256° C.
