Methitural
Methitural (INN; Neraval, Thiogenal), or methitural sodium, also known as methioturiate, is a barbiturate derivative which was marketed in the 1950s in Europe (in Germany and Italy) as an ultra-short-acting intravenous anesthetic.[1][2][3]

Synthesis
Methitural synthesis: Zima, Von Werder, U.S. Patent 2,802,827 (1957 to E. Merck).
A somewhat more complex side chain is incorporated by alkylation of the carbanion of the substituted cyanoacetate (1) with 2-chloroethylmethyl sulfide (2). Condensation of the resulting cyanoester (3) with thiourea followed by hydrolysis of the resulting imine affords methitural.
