Eterobarb (Antilon) is a barbiturate derivative. It has mainly anticonvulsant action with less sedative effects than the closely related compound phenobarbital. It saw reasonable success in clinical trials, but is not in widespread medical use.^[1][2]

Synthesis

Eterobarb can be synthesized by reacting phenobarbital with chloromethyl methyl ether in presence of a base.^[3]
