実験手順

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 at 0° C., a solution of cyclobutane carboxylic acid (10 g, 0.1 mol) in THF (15 ml). The resulting mixture was stirred at RT for 2 h then bromoethyl cyclopropane (15 g, 0.11 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 EtOAc. The organic layer was washed with water and brine to afford the title compound as light yellow oil (19.2 g), which was used in the next step without purification.
