Citenamide is a tricyclic chemical agent that is very similar in character to and most closely resembles carbamazepine (Tegretol), which a non-addictive anticonvulsant agent used to treat epileptic seizures, schizophrenia, phantom limb pain and alcoholism. Citenamide contains an amide functional group whereas carbamazepine contains a urea. Citenamide is an old drug and there is little pharmacological data surrounding its use in medicine.{{cite journal | vauthors = Wilhelm M, Schmidt P | title = [Synthesis and properties of 1-aminoalkyl-dibenzo(b,e)bicyclo(2,2,2) octadienes] | journal = Helvetica Chimica Acta | volume = 52 | issue = 6 | pages = 1385–1395 | date = January 1969 | pmid = 5820776 | doi = 10.1002/hlca.19690520602 }}{{cite journal | vauthors = Davis MA, Winthrop SO, Thomas RA, Herr F, Charest MP, Gaudry R | title = Anticonvulsants.

Synthesis
Organometallic formation between 5-chlorodibenzosuberene [18506-04-2] (1) and butyl lithium, is proceeded by a dry ice quench to give the acid, PC12515652{{Cite web | title = 5H-dibenzo[a,d]cycloheptene-5-carboxylic acid | url = https://pubchem.ncbi.nlm.nih.gov/compound/12515652 | work = PubChem | publisher = U.S. National Library of Medicine }} (2). Halogenation with thionyl chloride and Schotten-Baumann reaction with ammonia gives the amide, and hence citenamide (3).
