Procedure

To a solution of 2-(1-bromo-ethyl)-4,4dimethyl-4H-oxazol-5-one (3.00 g; 13.6 mmol) and 50 mL acetonitrile was added O-ethyl xanthic acid potassium salt (2.18 g; 13.6 mmol). The mixture was stirred under a nitrogen atmosphere at room temperature for 5 hours. The reaction mixture was filtered and the solid was washed with 10 mL acetontrile 10 mL. The combined filtrate was concentrated under reduced pressure to afford 2.89 g (81%) of dithiocarbonic acid S-[1-(4,4-dimethyl-5-oxo-4,5-dihydro-oxazol-2-yl)-ethyl] ester O-ethyl ester as a yellow oil.
