Procedure

To a solution of 3-(3-bromo-5-fluoro-pyridin-2-yl)-azetidine-1-carboxylic acid tert-butyl ester (58) (660 mg, 2 mmol, Preparation 17) and piperidin-4-yl-methanol (35) (230 mg, 2 mmol) in DMSO (20 mL) was added Et3N (404 mg, 4 mmol). The reaction mixture was stirred at 100° C. overnight. The reaction mixture was diluted with water, extracted with EtOAc (50 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 (EtOAc:PE=3:1) on silica gel to give (76) (490 mg, 1.34 mmol, yield 67%). ESI-MS (M+1): 366 calc. for C19H28FN3O3 365.
