Application of 138116-34-4, 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 138116-34-4 as follows.
Step 5: To a stirred solution of (4-aminopyridin-3-yl)methanol (200 mg, 1.61 mmol) in dimethylformamide were added imidazole (219 mg, 3.22 mmol, 2 eq) and tert-butyldimethylchlorosilane (267 mg, 1.77 mmol, 1.1 eq). The reaction mixture was stirred at room temperature for 5 h. The mixture was dissolved in ethylacetate and washed with water several times. The organic layer was dried over MgSO4 and filtered. The filtrate was removed in vacuo. The crude was purified by column chromatography get 3-((tert-butyldimethylsilyloxy)methyl)pyridin-4-amine (325 mg, 85%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,138116-34-4, its application will become more common.
