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-低碳酰氨基-4-苯基咪唑及其取代苯基衍生物,以及其药学上可接受的盐和制备这些化合物的方法。在一种方法中,可以通过将相应的β-氨基-β-(苯基或取代苯基)-乙基胺与所需的1,3-双(碳酰氧基)-S-甲基异硫脲或1-碳酰氧基-S-甲基异硫脲处理来制备化合物。这些化合物也可以通过将相应的2-氨基-4,5-二氢-4-(苯基或取代苯基)-咪唑与所需的二烷基碳酸酯处理来制备。该化合物可用作治疗、预防或缓解与中枢神经系统有关的哺乳动物的异常状况的精神治疗药物。
