Methanol → HCID 10749820, compound

Participants

Reaction Steps

To methanol (5 ml) in dry ice-acetone bath was added thionyl chloride (0.41 ml) dropwise over 5 minutes. After (E)-3-(6-Aminopyridin-3-yl)acrylic acid (700 mg) was added to the mixture, the reaction mixture was heated at reflux for 1 hour, and the solvent was removed under reduced pressure. The reaction mixture was adjusted to pH 8 with saturated sodium bicarbonate aqueous solution and extracted with dichloromethane. The organic layer was washed with water and brine, dried over magnesium sulfate and evaporated in vacuo. The precipitate was collected by vacuum filtration and washed with isopropyl ether to give methyl (E)-3-(6-aminopyridin-3-yl)acrylate (725 mg) as a solid.
