New downstream synthetic route of 2,4-Dichloro-5-methoxypyrimidine

The synthetic route of 19646-07-2 has been constantly updated, and we look forward to future research findings.

In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 19646-07-2, name is 2,4-Dichloro-5-methoxypyrimidine, the common compound, a new synthetic route is introduced below. Product Details of 19646-07-2

Intermediate 3: -Chloro-5-methoxypyrimidine2,4-Dichloro-5-methoxypyrimidine (43g, 0.24mol), zinc dust (86g, 1.32mol), ethanol (200 mL) and water (200 mL) were heated under reflux for 4h. The hot mixture was filtered and the ethanol was removed under reduced pressure. After cooling, the product was extracted into diethyl ether. Recrystallisation from light petroleum (b.p.: 40-60°C) gave 2-chloro-5-methoxypyrimidine (20g, 58percent).Mass: (ES+) 145 (M+H)+ NMR: 5H ( 6-DMSO) 3.92 (3H, s) and 8.55 (2H, s).

The synthetic route of 19646-07-2 has been constantly updated, and we look forward to future research findings.
