실험 절차

A slurry of 500 mg (1.21 mmol) 4-(5-bromo-pyridin-3-yl)-2-(5-chloro-2-fluoro-phenyl)-[1,8]naphthyridine, 370 mg (1.33 mmol) dimethyl-{3-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrazol-1-yl]-propyl}-amine and 512 mg (2.41 mmol) tri-potassium-phosphate-trihydrate in 5 ml 1,2-dimethoxyethane is heated to 85° C. under nitrogen. Then 42.3 mg (0.06 mmol) bis-(triphenylphosphine)-palladium(II)-chloride and 17 μl triethylamine were added. The reaction mixture was stirred for 2 hours at 85° C. The reaction mixture was partitioned between water and dichloromethane. The organic phase was dried over sodium sulfate and evaporated. The residue was crystallized from acetonitrile yielding [3-(4-{5-[2-(5-chloro-2-fluoro-phenyl)-[1,8]naphthyridin-4-yl]-pyridin-3-yl}-pyrazol-1-yl)-propyl]-dimethyl-amine as light grey crystals; HPLC-MS: 1.64 min, [M+H] 487.
