Electric Literature of 1256561-65-5, 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. 1256561-65-5, name is 3-(Bromomethyl)-5-fluoropyridine hydrobromide. A new synthetic method of this compound is introduced below.
A mixture of 3-(bromomethyl)-5-fluoropyridine hydrobromide (3.4 mmol), 6-methyl- 2-sulfanylpyrimidin-4-ol (370 mg, 2.6 mmol), and triethylamine (1.7 mL, 12.0 mmol) in absolute ethanol (40 mL) was stirred at room temperature overnight. The solid material was removed by filtration. The filtrate was recovered, evaporated, co- evaporated with EtOAc (20 mL), and then dried in vacuo. The solid residue was treated with water (100 mL). The solid product was recovered by filtration, washed with water (1 x 20 mL) and diethyl ether (2 x 20 mL), and then dried in vacuo, affording the 2-{[(5-fluoropyridin-3-yl)methyl]sulfanyl}-6-methylpyrimidin-4-ol (200 mg, 23% yield); 1H NMR (400 MHz, OMS0-d6): delta 2.21 (s, 3H), 4.41 (s, 2H), 6.02 (s (br), IH), 7. 80 (m, IH), 8.05 (dd, IH, / = 2.0 Hz, 7.6 Hz), 8.46 (d, IH, J = 2.7 Hz), 8.54 (t, IH, J = 1.6 Hz); M+ 252. The product was used 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,1256561-65-5, its application will become more common.
