3-dihydro-4-phenyl-2H-1,5-benzodiazepine-2-thione. After separation of the two components and further reaction, their structure was established by chemical degradation of 7-chloro-2-(2-diethylaminoethylthio)-4-phenyl-3H-1,5-benzodiazepine to 5-chloro-1,3-dihydro-1-methyl-2H-benzimidazol-2-one. The structure was also confirmed by single X-ray analysis of 7-chloro-2-(2-diethylaminoethylthio)-4-phenyl-3H-1,5-benzodiazepine
如预期的那样,使4-氯-1,2-苯二胺与3,3-二巯基-1-苯基-2-丙烯-1-酮反应,得到7-氯和8-氯-1,3-二氢的混合物-4-苯基-2 H -1,5-苯并二氮杂-2-硫酮。分离两种成分并进一步反应后,通过将7-氯-2-(2-二乙基氨基乙硫基)-4-苯基-3 H -1,5-苯并二氮杂卓化学降解为5-氯-1,3来确定其结构。 -二氢-1-甲基-2 H-苯并咪唑-2-一。该结构也由7-氯-2-(2- diethylaminoethylthio)-4-苯基- 3的单晶X射线分析确认ħ -1,5-苯并二氮杂。
