LORMETAZEPAM Usage And Synthesis

Chemical Properties

Pale Green Solid

Originator

Loramet ,Wyeth, W. Germany,1980

Uses

An analog of Lorazepam (L469850). Sedative, hypnotic. Controlled substance (depressant).

Definition

ChEBI: Lormetazepam is a 1,4-benzodiazepinone compound having a methyl substituent at the 1-position, a hydroxy substituent at the 3-position, a 2-chlorophenyl group at the 5-position and a chloro substituent at the 7-position. It has a role as a sedative. It is a 1,4-benzodiazepinone and an organochlorine compound.

Manufacturing Process

To a suspension of 3.4 g of 3-acetoxy-7-chloro-1,3-dihydro-5-(ochlorophenyl)-2H-1,4-benzodiazepin-2-one in 80 ml of alcohol was added 6 ml of 4 N sodium hydroxide. After complete solution had taken place a solid precipitated that redissolved upon the addition of 80 ml of water. The solution was acidified with acetic acid to give white crystals. After recrystallization from alcohol the compound melted at 192°C to 194°C.

Therapeutic Function

Hypnotic
