Procedure

A solution of 4-(5-bromo-[1,2,4]triazolo[1,5-a]pyrazin-8-ylamino)-benzoic acid (0.230 g, 0.69 mmol), 3-hydroxybenzotriazole (0.103 g, 0.76 mmol), 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrate (0.146 g, 0.76 mmol) in DMF (5 mL) and 3-picolylamine (0.077 mL, 0.76 mmol) is stirred at room temperature for 21 hours. The solvent is removed in vacuo and the residue is triturated with diethyl ether, ethyl acetate and dichloromethane. A pale yellow solid is obtained, washed with water and dried to afford the title compound (241 mg, 82%).
