| | CLOXAZOLAM Usage And Synthesis |
| Originator | Sepazon,Sankyo,Japan,1974 | | Uses | CLOXAZOLAM is a benzodiazepine derivative with anxiolytic, hypnotic and antihypertensive properties used as an anti-anxiety drug. It is metabolized into the active metabolite Delorezepam (D230675). Controlled Subs tance.
| | Definition | ChEBI: Cloxazolam is an oxazolobenzodiazepine and a hemiaminal ether. | | Manufacturing Process | As described in US Patent 3,772,371: To a solution of 5.8 g of 5-chloro-2-
bromoacetylamino-o-chlorobenzophenone in 120 ml of ethanol were added
0.95 g of ethanolamine and 1.3 g of sodium acetate. The resulting mixture
was heated under reflux for 16 hours.
After completion of the reaction, the solvent was distilled off and the residue
was extracted with dichloromethane. The extract was washed with water,
dried over anhydrous sodium sulfate and the solvent was distilled off to give
3.25 g of the desired product melting at 202° to 204°C with decomposition. | | Therapeutic Function | Tranquilizer |
