Application of 63810-78-6, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 63810-78-6, name is 5-Bromo-4-chloro-2-(methylthio)pyrimidine. A new synthetic method of this compound is introduced below.
To a stirred solution of 5-bromo-4-chloro-2-(methylthio)pyrimidine (6 g, 25 mmol) in THF (200 mL) at 0C, NaH (1.48 g, 60% in mineral oil, 37 mmol) was added and the reaction was stirred at 0C for lh. To this mixture, a solution of 2,2,2- trifluoroethan-l-ol (5.7 g, 25 mmol) in THF (20 mL) was added and the reaction was stirred at room temperature for 2 h. After completion of the reaction, the reaction mixture was quenched with ice cold water (250 mL) and extracted with ethyl acetate (2 x 500 mL). The combined organic layer was washed with brine solution (200 mL), dried over sodium sulfate and evaporated to afford 5-bromo-2-(methylsulfonyl)-4- (2,2,2-trifluoroethoxy)pyrimidine_as white solid (yield: 8 g, Crude). LCMS (ES) m/z = 303.26; NMR (400 MHz, DMSO-d6): delta 2.50 (s, 3H), 5.12-5.19 (m, 2H), 8.69 (s, 1H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,63810-78-6, its application will become more common.
