실험 절차

To a anhydrous THF (5 mL) solution of N-(3-hydroxybicyclo[1.1.1]pentan-1-yl)acetamide (1) (1 mmol) is added NaH (60% dispersion in mineral oil, 3 mmol) portionwise at 0° C. After addition, the mixture is stirred until the evolution of gas stops. Iodoethane (1 mmol) is then added by syringe slowly. The reaction is monitored by LCMS and TLC. After consumption of starting material, the reaction mixture is quenched by adding water (3 mL) and extracted with ethyl acetate (3×). The organic layers are combined, dried (magnesium sulfate), filtered, and concentrated. The crude residue is subjected to flash chromatography (silica gel, EtOAc/hexanes) to afford compound 2.
