9/17 News The origin of a common compound about 1753-50-0

At the same time, in my other blogs, there are other synthetic methods of this type of compound,1753-50-0, 2-Chloropyrimidine-5-carbonitrile, and friends who are interested can also refer to it.

Synthetic Route of 1753-50-0, 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.

To a stirred solution of compound OE (0.80 g, 2.93 mmol) and 2-chloropyrimidine-5-carbonitrile (AF, 0.45 g, 3.22 mmol) in EtOH (10 mL), DIPEA (2.7 mL, 14.65 mmol) was added and the reaction mixture was stirred at 85 C for 16 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 (40% EtOAc/hexane) to afford compound OF (0.82 g, 74.5%) as an off-white solid. 1H NMR (400 MHz, DMSO-d6): _ 9.01 (d, = 8.8 Hz, 1H), 8.64 (d, = 22.8 Hz, 2H), 7.85 (d, 7 = 18.0 Hz, 2H), 7.55-7.47 (m, 2H), 7.24-7.18 (m, 2H), 5.54-5.51 (m, 1H), 4.40-4.32 (m, 2H); LC-MS: m/z 376.8 [M+H]+.
