A mixture of 4-(4-bromo-3-fluorophenyl)pyridine (190 mg, 0.00075 mol), ethyl (3S)-piperidine-3-carboxylate hydrochloride (180 mg, 0.00090 mol), sodium tert-butoxide (140 mg, 0.0015 mol), palladium acetate (5 mg, 0.00002 mol) and 2-(di-tert-butylphosphino)biphenyl (7 mg, 0.00002 mol) was evacuated and charged with nitrogen and 1,4-dioxane (5 mL, 0.06 mol). The resulting mixture was refluxed overnight. After cooling to ambient temperature, the mixture was filtered and the filtrate was adjusted with TFA to pH=7.0 and purified by CombiFlash (ethyl acetate in hexanes: 60%) to afford the desired product. LCMS: m/z 329.2 (M+H)+.
