반응 단계

Glycine ethyl ester hydrochloride (140 mg, 1 mmol) and ethyl isothiocyanatoacetate (145 mg, 1 mmol) were dissolved in acetonitrile (6 mL), triethylamine (0.6 mL) was added thereto, and the mixture was stirred at room temperature (25° C.) for 10 minutes. After the reaction was completed the solvent was removed by evaporation under reduced pressure, and the residue was subjected to silica gel column chromatography using ethyl acetate/hexane (1/1 (volume ratio)) as an eluent, to give ethyl-2-(5-oxo-2-thioxoimidazolidin-1-yl)acetate in a yield of 170 mg (yield 84.2%).
