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. 1753-50-0, name is 2-Chloropyrimidine-5-carbonitrile. A new synthetic method of this compound is introduced below., Computed Properties of C5H2ClN3
To a stirred solution of compound FO (0.5 g, 3.02 mmol) in ethanol (10 mL), 2-chloropyrimidine-5-carbonitrile (AF, 0.5 g, 3.63 mmol) and DIPEA (2.63 mL, 15.1 mmol) were added and the reaction mixture was heated to 90C for 12 h. The progress of the reaction was monitored by TLC. After completion of the reaction, the reaction mixture was concentrated under reduced pressure. The crude product was purified by silica gel column chromatography using 30% EtOAc/hexane to afford compound FP (0.2 g, 24.6%) as a pale yellow solid. LC-MS: m/z 269.03 [M+H]+.
