실험 절차

A solution of lithium di-isopropylamide (100 mL, 2.0 M, 200 mmol) in heptane/tetrahydrofuran/benzene was diluted with 100 mL of anhydrous THF. To the LDA solution at 0° C. was added dropwise 10 g (100 mmol) of cyclobutanecarboxylic acid in 15 mL of anhydrous THF over 20 minutes under Argon. The mixture was sired at room temperature for 3 hours. To the reaction mixture was added 11.4 mL (100 mmol) of butyl iodide at 0° C. The reaction mixture was warmed to RT and stirred overnight. HCl (2N) was used to adjust the pH to 2˜3. The mixture was extracted with EtOAc (3×200 mL). The combined organic phase was washed with 100 mL of brine, dried (MgSO4) and concentrated. Thus obtained crude product was used directly for next step.
