A mixture of 4-(5-bromoimidazo[1,2-a]pyrazin-8-ylamino) benzoic acid (116 mg, 0.35 mmol), 4-aminomethylphenol (43 mg, 0.35 mmol), and N,N-diisopropylethylamine (0.094 mL, 0.525 mmol) in DMF (1 mL) is cooled to 0° C., and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (160 mg, 0.42 mmol) is added. The cooling bath is removed, and the reaction mixture stirred at 25° C. for 18 hours. After this time the solvent is removed in vacuo, and the residue triturated with MeOH. The resultant solid is collected by filtration and identified as the desired phenol.
