3-Pyridinemethanamine → HCID 15519648, compound

Participants

Reaction Steps

3.74 g of 4-[(2-methoxyethoxy)methoxy]cinnamic acid and 1.68 g of 3-(aminomethyl)pyridine were dissolved in 30 ml dimethylformamide, and stirred with 2.7 ml diethylphosphoryl cyanide and subsequently with 2.5 ml triethylamine on ice, followed by further stirring at room temperature for 1 hour. Saturated aqueous sodium bicarbonate was added to the reaction mixture, which was then extracted with ethyl acetate, washed with water, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give a residue, which was then purified via column chromatography on silica gel (chloroform:methanol=50:1) to provide (E)-3-[4-[(2-methoxyethoxy)methoxy]phenyl]-N-(3-pyridylmethyl)-2-propenoic acid amide as a pale yellow oil (4.54 g, 89%).
