A solution of 4-benzothiazol-2-yl-1H-pyrazol-3-ylamine (1.1 g, 5.0 mmol) in 20 mL of formic acid was heated to 70° C. overnight. The formic acid was evaporated under reduced pressure and the resulting crude material was recrystallized from ethanol to yield 1.1 g (90%) of N-(4-benzothiazol-2-yl-1H-pyrazol-3-yl)-formamide.
