Procedure
A 100-mL round-bottom flask was charged with 3-(benzyloxy)cyclobutanone (2.00 g, 11.4 mmol), tetrahydrofuran (20 mL), and methanol (1 mL), and the solution was cooled to 0° C. Sodium borohydride (0.475 g, 12.5 mmol) was added portionwise, and the resulting mixture stirred for 30 min at room temperature. The reaction mixture was poured into water (30 mL), and extracted with ethyl acetate (2×30 mL). The combined organic layers were dried over anhydrous sodium sulfate, filtered, and concentrated to afford 3-(benzyloxy)cyclobutanol (1.83 g, 90%) as yellow oil. MS (ESI, pos. ion) m/z 179 [M+H]+.
