Solutions of α-mercapto-ketone anions, generated from O-ethyl S-2-oxoethyl dithiocarbonates and piperidine, react with cyanamides to give 2-aminothiazoles with substituents on the heterocycle or the exo-nitrogen atom.

Although α-mercapto ketones react with cyanamides to give substituted 2-aminothiazoles the yields are satisfactory in only the simplest cases. However, a range of 2-aminothiazoles with substitutents on the ring or the exo-nitrogen atom was obtained efficiently by the following one-pot procedure: a solution of an α-mercapto ketone anion was generated by treating an O-ethyl S-2-oxoethyl dithiocarbonate
