実験手順
To a solution of 2-(3-((3-(piperidin-4-yl)pyrazin-2-yl)oxy)azetidin-1-yl)quinoline hydrochloride (see PREPARATION P4.1; 100 mg, 0.29 mmol) in dry DCM (10 mL) was added Et3N (1 mL). The reaction mixture was cooled to 0° C. with an ice bath, and methyl carbonochloridate (54 mg, 0.58 mmol) was added dropped to the reaction mixture. After 1 hour, 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 methyl 4-(3-((1-(quinolin-2-yl)azetidin-3-yl)oxy)pyrazin-2-yl)piperidine-1-carboxylate (93 mg, 0.23 mmol, 79% yield) as a white solid. ESI-MS (M+1): 404 calc. for C23H25N5O2 403.
