OXAZOLAM METHANOL SOLUTION Chemical Properties,Uses,Production

Originator

Serenal,Sankyo,Japan,1970

Uses

A psychotropic agent with anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. It is a precursor to the active substance Desmethyldiazepam (D291595).

Definition

ChEBI: Oxazolam is an organic molecular entity and a hemiaminal ether.

Manufacturing Process

To a solution of 12.0 g of 5-chloro-2-chloroacetylaminobenzophenone and 3.2 g of isopropanolamine in 100 ml of ethanol was added 3.3 g of sodium acetate.
The resulting mixture was heated under reflux with stirring for 12 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.
The residue was recrystallized from ethanol to give 10.6 g of the desired product melting at 186°C to 188.5°C.

Therapeutic Function

Tranquilizer

Safety Profile

Moderately toxic by intraperitoneal route. Mildly toxic by ingestion.An experimental teratogen. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of Clí and NOx.
