Here is a compound 56686-16-9, name is 5-Bromo-2,4-dimethoxypyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
General procedure: To a stirred anhydrous THF containing 5-bromo-2,4-dimethoxypyrimidine (0.29g, 1.3mmol) was added dropwise a 2.5M n-BuLi/hexane solution (0.6mL, 1.4mmol) at 195K under argon atmosphere. After 30min, 8a (0.52g, 1.3mmol) was added and the reaction mixture was stirred for 2h at this temperature. The reaction was allowed to warm to room temperature and quenched by addition of water. The product was extracted with diethyl ether. Then the combined organic layers were dried over MgSO4, filtered and concentrated. Column chromatography on SiO2 with petroleum ether and ethyl acetate (v/v=6/1) as the eluent afforded 0.35g of 1o as a colorless solid in 52% yield.
According to the analysis of related databases, 56686-16-9, the application of this compound in the production field has become more and more popular.
