실험 절차
3-benzyloxy-cyclobutanecarboxylic acid (1.67 g) in dry tetrahydrofuran (100 mL) was treated with borane-dimethylsulfide complex (1.3 mL) at 50° C. for 16 hours. Water (4 mL) and saturated sodium hydrogen carbonate (3 mL) were added and the mixture was extracted with ethyl acetate. The organic extracts were washed with brine, dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with ethyl acetate in cyclohexane (0 to 1:1 by volume) to give the title compound (1.46 g). 1H NMR (400 MHz, CHCl3-d): δ 7.29 (d, 5H), 4.36 (d, 2H), 4.08 (t, 1H), 3.91-3.82 (m, 1H), 3.53 (t, 2H), 2.39-2.30 (m, 1H), 2.33-2.22 (m, 1H), 2.10-2.02 (m, 2H), 1.72-1.63 (m, 1H).
