24-Sep-21 News New downstream synthetic route of 55717-45-8

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 55717-45-8, 6-Bromopyridin-3-ol, other downstream synthetic routes, hurry up and to see.

Synthetic Route of 55717-45-8, Adding some certain compound to certain chemical reactions, such as: 55717-45-8, name is 6-Bromopyridin-3-ol,molecular formula is C5H4BrNO, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 55717-45-8.

2-Bromo-5-hydroxypyridine (5 mmol) is dissolved in DMF (10 ml) and NaH (1.4 eq., 60% suspension in liquid paraffin) is added. After 30 min iodomethane (2 eq.) is added and the reaction solution is stirred 3 days. The reaction solution is pored into water and extracted with methyl-tert-15 butyl ether. The combined organic layers are dried over MgSO4 and the solvent is removed in vacuo. 2-Bromo-5-methoxy-pyridine is obtained as yellow oil in a yield of 79 %; HPLC (method C): 1.49 min; LC-MS (method A): 1.16 min, 187.95 (M+H+).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 55717-45-8, 6-Bromopyridin-3-ol, other downstream synthetic routes, hurry up and to see.
