実験手順

To a solution of 1-(quinolin-2-yl)azetidin-3-ol (see PREPARATION P1.2, step 1; 320 mg, 1.60 mmol) in DMF (10 mL) was added Cs2CO3 (1.04 g, 3.2 mmol) and 3-bromo-4-chloropyridine (307 mg, 1.60 mmol). The mixture was stirred at 90° C. overnight and then diluted with water (20 mL) and extracted with EtOAc (2×30 mL). The combined organic extracts were washed with water (30 mL) and brine (30 mL), dried over Na2SO4, and filtered. The filtrate was evaporated in vacuo and the residue was purified by flash column chromatography on silica gel (5% to 30% EtOAc in petroleum ether) to give the title product (350 mg, 0.98 mmol, 61% yield) as white solid. ESI-MS (M+1): 356 calc. for C17H14BrN3O 355.
