Reaction Steps
To a suspension of ethylene glycol (865 μL, 15.5 mmol) in tetrahydrofuran (19 mL) was added sodium bis(trimethylsilyl)amide (2.0 M in tetrahydrofuran, 4.66 mL, 4.7 mmol) at room temperature. The mixture was stirred for 15 minutes, then 2-chloro-4-(methylsulfonyl)pyrimidine (747 mg, 3.88 mmol) was added. The reaction mixture was stirred for 1 h at room temperature, concentrated, then purified by column chromatography on silica gel (Biotage 50 G, eluting with 0:100 to 100:0 ethyl acetate:hexanes) to give 2-[(2-chloropyrimidin-4-yl)oxy]ethanol (416 mg, 2.37 mmol, 61% yield) as a white solid. MS ESI: [M+H]+ m/z 175.0.
