5-Bromo-7-methyl-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (0.19 g, 0.84 mmol), 1,4-benzodioxane-6-boronic acid (0.18 g, 1.00 mmol), palladium(tetrakis)triphenylphosphine (97 mg, 0.084 mmol), potassium phosphate (0.36 g, 1.67 mmol), dimethylacetamide (3 ml) and water (1 ml) were added to a microwave vial containing a stirrer bar. The reaction was heated to 150° C. for 10 min. Water was added to the reaction mixture and the product extracted into ethyl acetate (×2). The organics were combined, washed several times with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The residue was triturated with diethyl ether and collected by filtration to give the desired product. LCMS RT: 2.82 min, MI: 283.17, Method: 2
