実験手順

A solution of trifluoro-methanesulfonic acid 3-(1-methyl-1H-pyrazol-4-yl)-quinolin-6-yl ester (15.9 g, 44.79 mmol), diisopropylethylamine (15.5 mL, 89.58 mmol) in DMF (150 mL) under nitrogen was degassed by bubbling with nitrogen for 30 min. Tris(dibenzylideneacetone)dipalladium (2.0 g, 2.24 mmol, Strem catalyst) and Xantphos (2.54 g, 4.48 mmol) were added together in one portion, followed by 6-methyl-[1,2,4]triazolo[4,3-b]pyridazine-3-thiol (7.44 g, 44.79 mmol) under a stream of nitrogen. The reaction mixture was stirred at 100° C. for 4 h. The reaction mixture was filtered while hot and the filtrate was cooled to precipitate. The solid was collected and washed with methanol to give an off-white solid, which was purified via column chromatography to get 13.3 g of 3-(1-methyl-1H-pyrazol-4-yl)-6-(6-methyl-[1,2,4]triazolo[4,3-b]pyridazin-3-ylsulfanyl)-quinoline (79% yield).
