Reference of 13036-50-5, 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. 13036-50-5, name is 2-Chloro-4-phenylpyrimidine. A new synthetic method of this compound is introduced below.
A mixture of 2-chloro-4-phenylpyrimidine (71 mg, 0.37 mmol), Intermediate 20 (100 mg, 0.34 mmol) and DIPEA (120 muIota_, 0.68 mmol) in NMP (1 mL) was heated at 130C for 3 hrs. The reaction mixture was allowed to cool to ambient temperature and diluted with water (10 mL). The crude product was extracted into diethyl ether (20 mL), dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by chromatography on the Biotage Companion (12 g column, 0 to 100% diethyl ether in isohexane) to afford the title compound as a gum (65 mg). LCMS (Method A): Two peaks at 2.45 min and 2.66 min, 451 [M+H]+.1H NMR (400 MHz, DMSO-d6, 374 K) 8.36 (d, 0.8 H), 8.30 (bd, 0.2 H), 8.15-8.07 (m, 1 .6 H), 7.97 (bm, 0.3 H), 7.56-7.46 (m, 3.92 H), 7.46-7.24 (m, 7.38 H), 7.16-7.05 (m, 1.8 H), 6.33 (bs, 1 H), 4.41 (td, 1 H), 3.71 (m, 1 H), 3.50 (m, 1 .1 H), 3.26 (bm, 0.2 H), 2.84 (s, 0.3 H), 2.82 (s, 0.3 H), 2.63 (s, 0.3 H), 2.48 (s, 2.1 H), 1 .82 (bm, 0.7 H), 1.00 (d, 2.5 H), 0.78 (bd, 0.5 H), 0.56 (bs, 3 H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,13036-50-5, 2-Chloro-4-phenylpyrimidine, and friends who are interested can also refer to it.
