A simple protocol to prepare the privileged 2-aminothiazoles promoted by ferrous sulfate heptahydrate via C-N bond formation from vinyl azides and commercially available potassium thiocyanate has been developed. A wide range of vinyl azides are tolerated to afford the expected polysubstituted 2-aminothiazoles in reasonably good yields. The use of the non-toxic substrates and catalyst renders the reaction more environmentally friendly than traditional approaches.
