1-Lower alkyl-4,5-dihydro-5-phenyl-2-lower alkoxycarbonylaminoimidazoles, and substituted phenyl derivatives thereof, and pharmaceutically acceptable salts thereof, and methods of preparing such compounds. In one method, the compounds can be prepared by treating the corresponding .beta.-lower alkylamino-.beta.-(phenyl or substituted phenyl)-ethylamine with the desired 1,3-bis (alkoxycarbonyl)-S-methylisothiourea or 1-alkoxycarbonyl-S-methylisothiourea. The compounds can also be prepared by treating the corresponding 1-lower alkyl-2-amino-4,5-dihydro-5-(phenyl or substituted phenyl)-imidazole with the desired dialkylcarbonate. The subject compounds are useful as psychotherapeutic agents in treating or palliating abnormal conditions, in mammals, which involve the central nervous system.
1-较低烷基-4,5-二氢-5-苯基-2-较低烷氧羰基氨基咪唑,以及其取代苯基衍生物和其药用可接受盐,以及制备这些化合物的方法。在一种方法中,可以通过处理相应的β-较低烷氨基-β-(苯基或取代苯基)-乙胺与所需的1,3-双(氧羰基)-S-甲基异硫脲或1-氧羰基-S-甲基异硫脲来制备这些化合物。这些化合物也可以通过处理相应的1-较低烷基-2-氨基-4,5-二氢-5-(苯基或取代苯基)-咪唑与所需的二烷基碳酸酯来制备。这些化合物可用作治疗或缓解涉及中枢神经系统的哺乳动物中的异常状况的精神治疗剂。
