A highly efficient synthesis of Zileuton is described in which the key step involves a site-specific alkylation of hydroxyurea under acid catalysis. Various aryl alcohol electrophiles were tested and the reaction was found to be highly substrate-specific, favoring benzothiophene and benzofuran-based alcohols.
