合成路线1
Condensation between ortho-anisidine (I) and benzonitrile (II) in the presence of NaNH2 furnishes N-(2-methoxyphenyl)benzamidine (III). Subsequent condensation of (III) with p-tolyl isothiocyanate (IV) produces the imidoyl thiourea (V). This is then oxidized by bromine in CHCl3 to form the target thiadiazolium salt.
