Extracurricular laboratory: Synthetic route of 89510-90-7

At the same time, in my other blogs, there are other synthetic methods of this type of compound,89510-90-7, 2-Chloro-5-fluoro-4-pyridinamine, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 89510-90-7, 2-Chloro-5-fluoro-4-pyridinamine, 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, Formula: C5H4ClFN2, blongs to pyridine-derivatives compound. Formula: C5H4ClFN2

4th Step Morpholine (3 ml) was added to 2-chloro-5-fluoropyridin-4-amine (262 mg) obtained in the 2nd step, followed by microwave irradiation (Initiator, 235 C., 2 hours, 2.45 GHz, 0-240 W). A saturated ammonium chloride aqueous solution was added to the reaction solution, followed by extraction with ethyl acetate. The organic layers were washed with a saturated ammonium chloride aqueous solution and saturated saline and dried over anhydrous sodium sulfate. Next, the solvent was distilled away under reduced pressure and a light brown solid of 5-fluoro-2-morpholinopyridin-4-amine (311 mg) was thus obtained.
