Procedure

To a solution of (5Z)-5-(piperidin-4-ylmethylidene)-4-(prop-2-yn-1-ylamino)-1,3-thiazol-2(5H)-one dihydrochloride (420 mg) in DMF (10 mL) were added [2,4-bis(trifluoromethyl)phenyl]acetic acid (426 mg), N-ethyl-N-(1-methylethyl)propan-2-amine (1.17 mL) and N-[(dimethylamino) (3H-[1,2,3]triazolo[4,5-b]pyridin-3-yloxy)methylidene]-N-methylmethanaminium hexafluorophosphate (595 mg). The reaction mixture was stirred at room temperature overnight under a nitrogen atmosphere, water was added, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) and recrystallized from ethyl acetate/heptane to give the title compound (498 mg).
