実験手順

4-(Azetidin-1-yl)-5-(5-bromo-1-methyl-1H-pyrazol-4-yl)-7-methylimidazo[5,1-f][1,2,4]triazine (35 mg, 0.10 mmol) and 5-chloro-3-fluoro-2-(trimethylstannyl)pyridine (59.5 mg, 0.202 mmol) were combined in toluene (1 mL) in a sealable tube and treated with dichlorobis(triphenylphosphine)palladium(II) (99%, 3.50 mg, 0.0050 mmol). The tube was sealed, and the reaction mixture was heated at 120° C. for 24 hours. The reaction was cooled, filtered through Celite and the pad was washed with ethyl acetate. After removal of solvent from the filtrate under reduced pressure, the residue was purified via silica gel chromatography (Eluant: 1% methanol in ethyl acetate) to provide the product as a solid. Yield: 20 mg, 0.050 mmol, 50%. LCMS m/z 399.1 (M+1). 1H NMR (400 MHz, CDCl3) δ 2.21-2.30 (m, 2H), 2.59 (s, 3H), 3.86-4.14 (br m, 4H), 3.98 (s, 3H), 7.40 (dd, J=9.0, 2.0 Hz, 1H), 7.72 (s, 1H), 7.80 (s, 1H), 8.51-8.53 (m, 1H).
