Procedure

In a 20 mL vial, a solution of 3-methyl-1-({[(2Z)-5-methyl-3-[4-(trifluoromethyl)phenyl]-1,3-thiazol-2(3H)-ylidene]amino}carbonyl)-1H-imidazol-3-ium iodide (45 mg, 0.09 mmol, Example 18B) dissolved in acetonitrile (0.6 mL) was added followed by the addition of diisopropylamine (21 μL, 0.12 mmol) dissolved in acetonitrile (0.6 mL). Then to the solution was added N-benzylethanamine (14 mg, 0.1 mmol) dissolved in acetonitrile (0.5 mL). The vial was capped and shaken overnight at room temperature. The reaction was concentrated to dryness. The residue was purified by reverse phase HPLC (C18, gradient 10-95% acetonitrile/water/0.1% trifluoroacetic acid) to provide the title compound.
