Synthetic Route of 33097-13-1, 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. 33097-13-1, name is 4,6-Dichloro-2-(methylthio)pyrimidine-5-carbonitrile. A new synthetic method of this compound is introduced below.
To the solution of 4,6-dichloro-2-(methylthio)-5-pyrimidinecarbonitrile (2.20 g, 10.0 mmol) in DMF (10 mL) was added 2,6-difluoroaniline (2.17 mL, 20.0 mmol). The solution was stirred at 50 0C for about 60 minutes. The mixture was slowly added into a solution of MeOH (20 mL) and water (30 mL). The resultant solid was filtered and washed with MeOH / H2O (20 mL, 1 : 1) to give 4-chloro-6-[(2,6-difluorophenyl)amino]-2-(methylthio)-5-pyrimidinecarbonitrile as a white solid (2.82 g, 90 %). LC-MS m/z 313 (M + H)+; 1H-NMR (CDCl3) delta 2.33 (s, 3 H), 6.94 (s, 1 H), 7.04 (m, 2 H), 7.35 (m, 1 H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,33097-13-1, 4,6-Dichloro-2-(methylthio)pyrimidine-5-carbonitrile, and friends who are interested can also refer to it.
