2-Amino-3-picoline Usage And Synthesis

Chemical Properties	2-Amino-3-picoline is CLEAR YELLOW LIQUID AFTER MELTING
Uses	2-Amino-3-picoline is used in the synthesis of ketones from aldehydes.
Synthesis Reference(s)	Journal of the American Chemical Society, 95, p. 4453, 1973 DOI: 10.1021/ja00794a070
Hazard	Toxic by ingestion.
Purification Methods	Recrystallise the picoline three times from benzene, most of the residual benzene being removed from the crystals by standing over paraffin wax chips in an evacuated desiccator. The amine is also transferred to a separating funnel under N2, and left in contact with NaOH pellets for 3hours with occasional shaking. It is then placed in a vacuum distilling flask where it is refluxed gently in a stream of dry N2 before fractionally distilling it. [Mod et al. J Phys Chem 60 1651 1956, Beilstein 22/9 V 212].
