실험 절차

To a solution of LDA (100 ml; 2.0 M THF solution) in THF (100 ml) was added dropwise over a period of 20 minutes under cooling with ice, a solution of cyclobutane carboxylic acid (10 g, 0.1 mol) in THF (15 ml) and the mixture was stirred at RT for 2 h. To the mixture iodoethane (15.6 g, 0.1 mol) was added dropwise and the mixture was stirred at RT overnight. To the reaction mixture was added 2N HCl and the mixture was extracted with ethyl acetate. The organic layer was washed with water and brine to afford the title compound as a light yellow oil (22.4 g), which was used in the next step without purification.
