To a solution of 1-{[6-(2-methylcarbamoyl-pyridin-4-yloxy)-benzooxazol-2-ylamino]-methyl}-cyclohexanecarboxylic acid (1 eq) in DMF was added DIPEA (3 eq) and [dimethylamino-([1,2,3]triazolo[4,5-b]pyridin-3-yloxy)-methylene]-dimethyl-ammonium hexafluoro phosphate (1 eq). This was stirred at room temperature for 2 hours, then a 2 M solution of methylamine in THF (5 eq) was added and allowed to react overnight at 70° C. The mixture was diluted with ethyl acetate and washed twice with a saturated aqueous solution of ammonium chloride and once with brine, then dried with anhydrous sodium sulfate, filtered and concentrated, then purified by preparatory reverse phase HPLC. MH+=438.1.
