実験手順

A mixture of Cs2CO3 (3.2 g, 10.0 mmol), 2-chloro-quinoline (0.8 g, 5.0 mmol) and tert-butyl azetidin-3-ylcarbamate (0.8 g, 5.0 mmol) was dissolved in DMF (20 mL) and the resulting mixture was heated to 100° C. overnight. Then the mixture was diluted with water (20 mL) and extracted with EtOAc (2×50 mL). The combined organic extracts were combined and washed with water (20 mL) and brine (20 mL), dried over Na2SO4, and filtered. The filtrate was evaporated in vacuo and the residue was purified by flash column chromatography on silica gel (20% to 70% EtOAc in petroleum ether) to give tert-butyl (1-(quinolin-2-yl)azetidin-3-yl)carbamate (0.8 g, 2.9 mmol, 53% yield) as white solid. ESI-MS (M+1): 300 calc. for C17H21N3O2 299.
