To a suspension of 6-((6-bromo-1 H-[1 ,2,3]triazolo[4,5-b]pyrazin-1-yl)methyl)quinoline (68 mg, 0.2 mmol) (prepared from quinolin-6-ylmethanamine following the procedures of Compound 1 ) and 1-methyl-1 H-pyrazol-3-amine (20 mg, 0.22 mmol) in dioxane (5ml_) were added Cs2C03 (72 mg, 0.22 mmol) and H20 (0.5 ml_). The mixture was degassed and charged with N2 three times, then Pd2(dba)3 (0.02 mmol, 18 mg) and xantphos (0.04 mmol, 23 mg) were added. The resulting mixture was stirred at 120°C under one atmosphere of N2 overnight, then concentrated. The resulting residue was purified by chromatography to afford the title compound (10 mg). MS (m/z): 358 (M-M f.
