Related Products of 22536-65-8 ,Some common heterocyclic compound, 22536-65-8, molecular formula is C5H5ClN2O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

To a solution of 2-chloro-5-methoxypyrimidine (5.0 g, 34.6 mmol, 1.0 equiv) in MeOH (100 mL) and DMF (20 mL) were added triethylamine (10.5 g, 103.8 mmol, 3.0 equiv) and Pd(dppf)Cl2 (3.8 g, 5.2 mmol, 0.15 equiv). The suspension was degassed and purged with CO several times. The mixture was stirred under CO (3 Mpa) at l20C for 72 hours. The reaction mixture was filtered and the filtrate was concentrated. The residue was purified by column chromatography (eluted with PE/EtOAc = 20/1 ~ 10/1) to afford the title compound methyl 5-methoxypyrimidine-2-carboxylate as a light yellow solid (3.3 g, 57% yield). LCMS: m/z: 169.0 (M+H) +

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,22536-65-8, its application will become more common.
