実験手順

To a solution of (S)-3-(2,5-difluoro-4-(methylsulfonyl)phenoxy)-[1,4′-bipiperidin]-2-one (Preparation G; 30 mg, 0.077 mmol) in DMF was added 2,3-difluoro-5-(trifluoromethyl)pyridine (42 mg, 0.23 mmol) and DIEA (30 μL, 0.23 mmol) and the reaction was stirred at ambient temperature for 18 hours. The reaction was diluted with EtOAc and washed with brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by preparative TLC (EtOAc/DCM 4:1) to give (S)-3-(2,5-difluoro-4-(methyl-sulfonyl)phenoxy)-1′-(3-fluoro-5-(trifluoromethyl)pyridin-2-yl)-[1,4′-bipiperidin]-2-one as a white solid (20 mg, 0.035 mmol, 46% yield). Mass spectrum (apci) m/z=552.2 (M+H).
