Carbromal is a hypnotic/sedative originally synthesized in 1909 by Bayer and subsequently marketed as Adalin.[1][2] The drug was later sold by Parke-Davis in combination with pentobarbital, under the name Carbrital.[3] As of 2015, it was still used in Hungary in combination with aminophenazone under the name Demalgon.
Synthesis
Diethylmalonic acid [510-20-3] (1) is decarboxylated to 2-ethylvaleric acid [20225-24-5] (2). The Hell-Volhard-Zelinsky reaction converts this to 2-Bromo-2-Ethylbutyryl Bromide [26074-53-3] (3). Reaction with urea with affords carbromal (4).
