| 3-METHYL-1,3-THIAZOLANE-2,4-DIONE Usage And Synthesis |
| Uses | 3-methyl-1,3-thiazolidine-2,4-dione can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical production process. | | Synthesis | To a solution of 2,4-thiazolidinedione (1 equiv) in 5 mL of DMF was added potassium carbonate (1.1 equiv) and halogen (1.1 equiv). The suspension was stirred at 80 oC overnight. Solvent was evaporated and the residue was purified by flash column chromatography ( petroleum ether/EtOAc, 5:1) to afford the product 3. 3-Methylthiazolidine-2,4-dione (3a) Following the previous procedure, 2,4-thiazolidinedione (500 mg, 4.3 mmol) and iodomethane (0.3 mL, 4.7 mmol). 3a as white solid (460 mg, 82%). |
