acetyl carbromal Usage And Synthesis

Originator	Acetylcarbromal ,Pfaltz and Bauer
Definition	ChEBI: Acecarbromal is a N-acylurea.
Manufacturing Process	It was mixed 120 parts of urea and 258 parts of bromodiethylacetylbromide (prepared from diethylacetic acid anhydride and bromine). After 12 hours the mixture was heated for 3 hours at 100°C. The product was mixed with an aqueous solution of sodium bicarbonate and then was filtered. The obtained bromodiethylacetylurea was crystallized from diluted ethanol; melting point 114-118°C. The mixture of 474 parts of bromodiethylacetylurea, 1000 parts of acetic anhydride and 75 parts ZnCl2 was heated at 60°C for 1 hour. The product was stirred with 3000 parts of ice-water and then 1-acetyl-3-(α- bromo-α-ethylbutyryl)urea was filtered; melting point 108-109°C.
Therapeutic Function	Sedative, Hypnotic
