Into a 50-mL round-bottom flask was placed (2S)-2-phenyloxirane (4 g, 33.29 mmol, 1.00 equiv) and oxetan-3-ol (16 mL). This was followed by the addition of sodium hydride (1.3 g, 32.50 mmol, 1.00 equiv, 60%) in several batches. The resulting solution was stirred for 1 h at 80° C. in an oil bath. The reaction was then quenched by the addition of 50 mL of NH4Cl (sat., aq.). The resulting solution was extracted with 2×50 mL of ethyl acetate and the organic layers combined and concentrated under vacuum. The residue was applied onto a silica gel column with PE/EA (8:1). Purification afforded 1.6 g (25%) of (2R)-2-(oxetan-3-yloxy)-2-phenylethan-1-ol (73.2) as a yellow oil.
