Reaction Steps
A mixture of 3-bromopyridine (25.10 g), ethanolamine (34.89 g) and cupric sulfate (2.90 g) in water (140 ml) was refluxed for 5 hours under stirring. The reaction mixture was washed with chloroform and the aqueous layer was separated out. To the aqueous solution was added an aqueous solution of potassium carbonate (22 g) and then the mixture was saturated with sodium chloride, and extracted with a mixed solvent of chloroform and ethanol (1:1). The extract was evaporated and the residue was subjected to column chromatography on silica gel (200 g) using a mixed solvent of chloroform and ethanol (5:1) as an eluent. The fractions containing an object compound were collected and evaporated to give 3-(2-hydroxyethyl)aminopyridine (5.96 g) as an oil.
