To a 8 mL vial was added 3-(3-butyl-4-oxothiazolidin-2-ylideneamino)benzonitrile (55 mg, 0.20 mmol), 3-methyl-2-(methylthio)benzothiazol-3-ium p-toluenesulfonate (73 mg, 0.20 mmol), anhydrous MeCN (2 mL) and TEA (70 μL, 0.50 mmol). The reaction mixture was first warmed to 50° C. and the resulting solution was allowed to stir at room temperature for 16 h. The product mixture was concentrated under reduced pressure, chromatographed (silica gel, 1:99 MeOH/DCM) and then recrystallized from MeCN to give the title product (11.8 mg) as a yellow solid.
