実験手順

To a solution of ethyl 2-formylcyclopropanecarboxylate in methanol (0.7 M) was added at −0° C. sodium borohydride portionwise. The resulting reaction mixture was stirred at 0° C. for 30 min and then at RT for 1.5 h. The reaction was quenched with sat. aq. NH4Cl and then extracted with ether. The combined organic extracts were washed with water and brine, dried over MgSO4, and filtered. Concentrated of the filtrate in vacuo afforded the title compound as a colorless oil.
