Related Products of 75115-28-5, 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. 75115-28-5, name is N3-Benzylpyridine-3,4-diamine. A new synthetic method of this compound is introduced below.
General procedure: The vial containing the crude diaminopyridine was equipped with a magnetic stir bar and sealed with a teflon screw cap. Aldehyde (2 mol eqwith respect to the theoretical yield of the first reaction) and then nBuOH was added via syringe to give a diaminopyridine concentration of 0.3 M based on the theoretical yield of the first reaction. The reaction mixture was stirred at 110 C for 18-24 h with needle inserted in septum to expose reaction to air. The mixture was cooled to room temperature, diluted with ethyl acetate, and poured into aqueous saturated NaHCO3. The organic phase was separated and the aqueous phase was extracted twice more into ethyl acetate. The combined organic phases were driedover Na2SO4. The solvent was removed under reduced pressure. The residue was purified by flash column chromatography on silica gel, typically using EtOAc, 0 ->10% MeOH.
