This compound has unique chemical properties. The synthetic route is as follows. SDS of cas: 1321612-85-4
250 mg of 3-fluoro-5-iodopyridin-2-amine was dissolved in 5 ml of acetonitrile, and 40 mg of 2-bromo-2-(ethylthio)-1-[3-methyl-6-(trifluoromethyl)-3H-imidazo[4,5-c]pyridin-2-yl]ethanone was added at room temperature. After the addition, the reaction mixture was stirred under reflux with heating for one hour. After the reaction, the reaction mixture was mixed with 10 ml of water and extracted with chloroform (10 ml*2). The resulting organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The precipitated solid was collected by filtration to obtain 338 mg of the desired product as a brown solid. 1H-NMR (CDCl3): delta8.96 (s, 1H), 8.73 (d, J=1.5 Hz, 1H), 8.19 (d, J=0.9 Hz, 1H), 7.33 (dd, J=9.0, 1.5 Hz, 1H), 4.36 (s, 3H), 3.15 (q, J=7.5 Hz, 2H), 1.23 (t, J=7.5 Hz, 3H).
