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. 722550-01-8, name is 4-(Pyrrolidin-1-yl)pyridin-2-amine. A new synthetic method of this compound is introduced below., Recommanded Product: 4-(Pyrrolidin-1-yl)pyridin-2-amine
In the Schlenk reaction tube,Join7-(Pyrrolidin-1-yl)-2-aminopyridine163mg,273mg of silver carbonate, the system is replaced by nitrogen protection,Add 10 ml of 1,4-dioxane, 1-bromomethyl-phenylacetylene, 96 mg,The reaction was carried out at 100C for 12 hours. The reaction was stopped, the reaction system was filtered using celite, the filter residue was washed with 20-30 ml of dichloromethane, and the filtrates were combined.Elution with a gradient of ethyl acetate: petroleum ether = 1:8 to 8:1,Obtaining intermediates2-(4-bromomethylphenyl)-7-(pyrrolidin-1-yl)imidazo[1,2-a]pyridine122 mg, yield 69%.
