Reaction Steps
To a stirred solution of (RS)-2-chloro-5-(oxiran-2-yl)pyridine (4.0 g) in THF (15 ml) was added 2-aminoethanol (15.4 ml) and the mixture was stirred at room temperature overnight. The reaction mixture was then poured into EtOAc/THF (1:1) and the mixture was washed with saturated brine. The organic layer was dried over Na2SO4 and concentrated in vacuo to afford (RS)-1-(6-chloropyridin-3-yl)-2-(2-hydroxyethylamino)ethanol (5.05 g) as a yellow solid which was used in the next step without further purification. MS (ISP): 219.3 ([{37Cl}M+H]+), 217.2 ([{35Cl}M+H]+), 201.3 ([{37Cl}M+H—H2O]+), 199.1 ([{35Cl}M+H—H2O]+).
