Application of 887707-23-5, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 887707-23-5, name is 2-Hydroxy-5-iodo-3-(trifluoromethyl)pyridine. A new synthetic method of this compound is introduced below.
(0614) A mixture of Compound 37C (0.537 g), 5-iodo-3-(trifluoromethyl)pyridin-2-ol (1.156 g), and triphenylphosphine (1.574 g) in tetrahydrofuran (20 ml) was cooled to 0 C. To this solution was added (E)-di-tert-butyl diazene-1,2-dicarboxylate (0.921 g). The reaction mixture was stirred overnight. The solvent was removed, and the residue was purified with column flash chromatography on silica gel eluting with 4:1 hexanes/ethyl acetate to give the desired product.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,887707-23-5, 2-Hydroxy-5-iodo-3-(trifluoromethyl)pyridine, and friends who are interested can also refer to it.
