With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.324579-90-0,4-Cyclopropylthiazol-2-amine,as a common compound, the synthetic route is as follows.
To a stirred solution of Compound J (5.6 g, 40 mmol) and CuBr (8.5 g, 60 mmol) in CH3CN (100 mL) was added dropwise t-BuONO (6.2 g, 7.2 mL, 60 mmol) at 0 ¡ãC. Then the reaction mixture was warmed to room temperature and further stirred for additional 30 mins. After that, the precipitate was filtered and the solvent was removed under reduced pressure. The residue was purified by column chromatography (eluent: 100percent petroleum ether) to afford the desired product K (3.5 g, 43 percent) as a light yellow oil containing small amount of petroleum ether. 1H NMR (400 MHz, CDC13): delta 6.77 (s, 1H), 2.00-1.95 (m, 1H), 0.94-0.85 (m, 4H)., 324579-90-0
The synthetic route of 324579-90-0 has been constantly updated, and we look forward to future research findings.
