실험 절차

To a solution of 1-(3-((1-(quinolin-2-yl)piperidin-4-yl)oxy)pyrazin-2-yl)piperidin-4-ol (see EXAMPLE 1.1; 100 mg, 0.25 mmol) in dry acetonitrile (CH3CN) (10 mL) was added Cs2CO3 (162 mg, 0.5 mmol). The reaction mixture was cooled to 0° C. with an ice bath, and iodomethane (70 mg, 0.50 mmol) was added dropwise to the reaction mixture. 1 hour later, the reaction mixture was warmed to RT, and stirred overnight. Then the reaction mixture was washed with brine, dried over Na2SO4, filtered, and concentrated under vacuum to give the crude product. The crude product was purified via flash chromatography on silica gel (20% to 45% EtOAc in petroleum ether) to give 2-(4-((3-(4-methoxypiperidin-1-yl)pyrazin-2-yl)oxy)piperidin-1-yl)quinoline (81 mg, 0.19 mmol, 78% yield) as a white solid. ESI-MS (M+1): 420 calc. for C24H29N5O2 419.
