실험 절차
A solution of 11.9 g. (0.1 mol.) of phenylisocyanate in 75 ml. of toluene is added dropwise to the stirred suspension of 15.2 g. (0.12 mol.) of 2-methyl-5-nitroimidazole in 60 ml. of water at 10° to 12° C. When the addition is complete, the mixture is stirred for further 4 hours. The separated product is filtered off, washed and dried. 20.4 g. (82.9%) of 1-phenylcarbamoyl-2-methyl-5-nitroimidazole are obtained; m.p.: 218°-220° C.
