Versuchsvorschrift
There is known from the German Patent Specification No. 1,136,707 a process for producing 5H-dibenz[b,f]azepine-5-carboxamide by reaction of 5H-dibenz[b,f]azepine with phosgene to give 5-chlorocarbonyl-5H-dibenz[b,f]azepine and the subsequent reaction thereof with ammonia to obtain the stated compound. The reaction of 5H-dibenz[b,f]azepine with phosgene is performed in toluene firstly at 70° C., and then under reflux. The subsequent reaction of this compound with ammonia is carried out in ethanol at boiling temperature.
