実験手順

To a solution of 4-oxo-5-(trifluoromethyl)-1H-quinoline-3-carboxylic acid (100 mg, 0.3889 mmol) and 6-(7-azabicyclo[2.2.1]heptan-7-yl)-2-(trifluoromethyl)pyridin-3-amine (110.1 mg, 0.4278 mmol) in 2-methyltetrahydrofuran (1.0 mL) was added propyl phosphonic acid cyclic anhydride (50% solution in ethyl acetate, 495.0 μL, 0.7778 mmol) and pyridine (61.52 mg, 62.90 μL, 0.7778 mmol). The reaction was capped and heated at 60° C. for 16 h. The reaction was cooled to room temperature, diluted with ethyl acetate (10 mL) and quenched with saturated Na2CO3 solution (6 mL). After stirring for 20 min the organic layer was separated, dried over Na2SO4, filtered and concentrated. Purification by silica gel chromatography (0-20% ethyl acetate in dichloromethane) provided N-(6-(7-azabicyclo[2.2.1]heptan-7-yl)-2-(trifluoromethyl)pyridin-3-yl)-4-oxo-5-(trifluoromethyl)-1,4-dihydroquinoline-3-carboxamide (137 mg, 71% yield). LC/MS m/z 497.5 [M+H]+, retention time 1.92 min (RP-C18, 10-99% CH3CN/0.05% TFA over 3 min).
