Versuchsvorschrift

To a solution of 2-[3-(3-chloro-pyrazin-2-yl)-azetidin-1-yl]-quinoline (80 mg, 0.27 mmol) and 1-piperidin-4-yl-ethanone (WUXI APPTEC) (34.3 mg, 0.27 mmol) in DMSO (5 mL) was added Et3N (54.5 mg, 0.54 mmol). The reaction mixture was stirred at 100° C. overnight. The reaction mixture was diluted with water, extracted with EtOAc (20 mL×3). 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 to give 1-{1-[3-(1-quinolin-2-yl-azetidin-3-yl)-pyrazin-2-yl]-piperidin-4-yl}-ethanone (65.8 mg, 0.17 mmol, yield 62.9%).
