Versuchsvorschrift

Potassium carbonate (0.89 g, 6.45 mmol) was added at room temperature to an oven-dried, nitrogen cooled flask containing a suspension of ethylene glycol (1.3 mL, 23.4 mmol) in DMF (29 mL) and the mixture was then stirred for 15 minutes. 2-Chloro-4-(methylsulfonyl)pyrimidine (1.13 g, 5.86 mmol) was then added. The solution was stirred for 1.5 h at room temperature, then diluted with EtOAc (30 mL) and washed with 1:1 water:brine (3×50 mL). The organic extracts were dried over sodium sulfate, filtered, concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (0 to 100% EtOAc/hexanes) to afford 2-[(2-chloropyrimidin-4-yl)oxy]ethanol as a pale yellow solid. MS ESI calcd. for C6H8ClN2O2 [M+H]+ 175. found 175.
