실험 절차

To a suspension of NaH (1.5 mmol) in DMF is added 3-piperidin-1-yl-propan-1-ol (1.1 mmol). After 30 min, 2-bromo-5-piperidin-1-ylmethyl-pyridine (1 mmol) is added to the mixture. After 18 h, the reaction is extracted with ethyl acetate (100 mL) and washed with 1 N NaHCO3 (50 mL) and H2O(3×50 mL). The organic layer is dried, concentrated, and chromatographed on SiO2 to provide the title compound.
