Application of 25245-29-8, These common heterocyclic compound, 25245-29-8, name is 5-Iodo-1,2,3-trimethoxybenzene, 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.
Referential Example 49Synthesis of 4-iodo-2,6-dimethoxyphenol:; [] To a solution of 5-iodo-1,2,3-trimethoxybenzene (3.2 g) in 1,2-dichloroethane (40 mL) was added aluminum chloride (1.6 g). The mixture was stirred at 60C for 4 hours and concentrated under reduced pressure. The residue was dissolved in 1 M aqueous sodium hydroxide solution and washed with ether. The aqueous layer was then acidified and extracted with chloroform. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give the title compound as white crystalline powder. Yield: 1.0 g (31%)
The synthetic route of 25245-29-8 has been constantly updated, and we look forward to future research findings.
