Into a 50-mL 3-necked round-bottom flask, was placed FeCl3 (800 mg, 4.94 mmol, 0.10 equiv). This was followed by the addition of oxan-4-ol (5 g, 48.96 mmol, 1.00 equiv) at 0° C. To this was added oxirane (20 mL) dropwise with stirring at 0° C. The resulting solution was stirred overnight at room temperature. The reaction was then quenched by the addition of 10 mL of water. The resulting solution was extracted with 2×50 mL of ethyl acetate and the organic layers combined. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:30-1:1). Purification afforded 2.25 g (crude) of 2-(oxan-4-yloxy)ethan-1-ol (54.2) as a colorless oil.
