Reference of 3618-04-0, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 3618-04-0 as follows.
Step A: ethyl 4-(5 -bromopyridin-2-yloxy)cycl ohexanecarboxylateTo a solution of 5-bromo-2-hydroxypyridine (1.0 g, 5.747 mmol) and ethyl 4- hydroxycyclohexanecarboxylate (0.99 g, 5.75 mmol) in THF (50 mL) was added PPh3 (2.4 g,9.15 mmol) and DIAD (1.8 mL, 9.14 mmol). The reaction mixture was stirred at RT for 17 h.The solution was then concentrated and purified by silica gel column chromatography with anISCO system to yield ethyl 4-(5-bromopyridin-2-yloxy)cyclohexanecarboxylate as a colorless oil.
According to the analysis of related databases, 3618-04-0, the application of this compound in the production field has become more and more popular.
