Cysteamine → HCID 178522584, compound

Participants

Reaction Steps

Ethanol (20 mL) was added to 77 mg (1.0 mmol) of 2-aminoethanethiol, 216 mmol (1.0 mmol) of the dimethyl(2,2,2-trifluoroacetyl)carbonimidodithioate synthesized by the method described in Comparative Example 7 was added, and the mixture was stirred overnight at room temperature. Following reaction completion, the solvent was distilled off under reduced pressure, and purification was carried out by silica gel column chromatography (hexane/ethyl acetate=1:1), giving 100 mg of 2,2,2-trifluoro-N-(thiazolidin-2-ylidene)acetamide (yield, 51%). This reaction was carried out once more by the same synthesis method, giving a combined amount of 350 mg of 2,2,2-trifluoro-N-(thiazolidin-2-ylidene)acetamide.
