The new cyclopropyl derivatives have formula (I) wherein R is cyclopropyl or methylcyclopropyl. The preparation process comprises reacting 2,6-dibromohexanoyl chloride with 2,6-dimethylanyline in the presence of a base at 0°-25 °C to give 2,6-dibromohexanoyl-2,6-dimethylanilide which subsequently is caused to react with R-NH₂ (wherein R is as defined hereabove) at 70-100 °C to give the cyclopropyl derivatives having formula (I). The compounds (I) can be applied as antiarithmic agents and as local anaesthetic agents.
新的环丙基衍生物具有式 (I),其中 R 是环丙基或甲基环丙基。制备过程包括在 0°-25 °C 下,在碱存在下,使 2,6-二溴己酰氯与 2,6-二甲基苯胺反应,得到 2,6-二溴己酰基-2,6-二甲基苯胺,然后使其在 70-100 °C 下与 R-NH₂(其中 R 如上定义)反应,得到式(I)的环丙基衍生物。化合物(I)可用作抗焦虑剂和局部麻醉剂。
