4,5-Dihydro-2-lower alkoxycarbonylamino-4-phenylimidazole, 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.-amino-.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 2-amino-4,5-dihydro-4-(phenyl or substituted phenyl)-imidazole with the desired dialkylcarbonate. The subject compounds are useful as psychotherapeutic agents for treating, preventing or palliating abnormal conditions, in mammals, which are related to the central nervous system.
4,5-二氢-2-较低烷氧羰胺基-4-苯基咪唑,及其取代苯基衍生物和药用盐以及制备这些化合物的方法。在一种方法中,可以通过用所需的1,3-双(烷氧羰基)-S-甲基异硫脲或1-烷氧羰基-S-甲基异硫脲处理相应的β-氨基-β-(苯基或取代苯基)-乙胺来制备这些化合物。这些化合物也可以通过用所需的二烷基碳酸酯处理相应的2-氨基-4,5-二氢-4-(苯基或取代苯基)-咪唑来制备。这些化合物可用作治疗、预防或缓解与中枢神经系统相关的哺乳动物异常症状的精神治疗药物。
