Synthetic Route of 26493-11-8 ,Some common heterocyclic compound, 26493-11-8, molecular formula is C6H7N3OS, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
A mixture of intermediate 3 (8 g, 39.8 mmol), copper (II) bromide (10.43 g, 46.68 mmol) and 3-methyl-l-nitrosooxy-butane (6.8 g, 58.35 mmol) in ACN (100 mL) was stirred at room temperature for 1.5 hours. The solvent was evaporated in vacuo. The residue thus obtained was dissolved in AcOEt and washed with H20. The organic layer was separated, dried (Na2S04), filtered and the solvents evaporated in vacuo to yield 5 g (55%) of intermediate 4 that was used in the next step without further purification.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,26493-11-8, its application will become more common.
