実験手順
Ethyl 2-formyl-1-cyclopropanecarboxylate (2 ml, 15.11 mmol) was dissolved in methanol (35 ml) and cooled to 0° C. under N2. Sodium borohydride (1.2 g, 31.7 mmol) was added in portions and resulting solution stirred at 0° C. for 2 h. The solution was then diluted by the dropwise addition of water, followed by the addition of EtOAc (100 mL). The aqueous layer was separated and extracted with EtOAc (2×50 mL). The combined organic layers were washed with brine, dried over sodium sulphate and concentrated in vacuo to give the title compound. TLC: 20% EtOAc/hexanes, high Rf: 0.35, low Rf: 0.3.
