反応手順
Separately, glycine ethyl ester hydrochloride (140 mg, 1 mmol) and bis(carboxymethyl) trithiocarbonate (224 mg, 1 mmol) were dissolved in 2-propanol (6 mL), triethylamine (0.6 mL) was added thereto, and the mixture was heated to reflux for 1 hour while stirring. 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-(4-oxo-2-thioxothiazolidin-3-yl)acetate in a yield of 177 mg (yield 80.8%).
