N-Substituted imidazolecarboxamide compounds represented by the formula; ##STR1## wherein R.sub.1 is hydrogen atom, lower alkyl, lower alkenyl, aralkyl, R.sub.2 is hydrogen atom, lower alkyl, lower alkenyl, aralkyl, 1-adamantyl, R.sub.3 is hydrogen atom, lower alkyl, aralkyl; with the proviso that one of R.sub.1, R.sub.2 or R.sub.3 is not hydrogen when the other two are hydrogen, are produced by reacting aminomalonamide derivative with orthoformate derivative in high yields. The compounds (I) exhibit anti-tumor activity against experimental tumors such as Sarcoma 180 in mice.
式##STR1##表示的N-取代咪唑甲酰胺化合物,其中R1为氢原子、低级烷基、低级烯基、芳烷基,R2为氢原子、低级烷基、低级烯基、芳烷基、1-金刚烷基,R3为氢原子、低级烷基、芳烷基;但条件是当R1、R2或R3中的两个为氢时,另一个不能为氢。这些化合物(I)通过使氨基丙二酰胺衍生物与原甲酸衍生物反应高产率制备。化合物(I)对小鼠的实验性肿瘤如肉瘤180表现出抗肿瘤活性。
