1-Alkyl(aryl)imidazolidine-2,4-diones reacted with Vilsmeier-Haack reagent affording 1-alkyl(aryl)-2,4-dichloro-1H-imidazole-5-carbaldehydes whose reactions with sodium azide, sodium alkoholates, with phenols, thiols, and secondary cycloalkylamines led to the substitution of chlorine in the position 2 of the imidazole ring. The reaction with primary amines resulted in the condensation products at the
1-烷基(芳基)咪唑烷-2,4-二酮与Vilsmeier-Haack试剂反应,得到1-烷基(芳基)-2,4-二氯-1 H-咪唑-5-甲醛与叠氮化钠,醇钠,与苯酚,硫醇和仲环烷基胺的反应导致咪唑环2位上的氯取代。与伯胺的反应产生醛基上的缩合产物。
