Reaction Conditions

Temperature120 °C

Reaction Steps

4-(pyridin-2-yl)but-3-yn-1-amine (640 mg, 4.40 mmol), 2-chlorobenzo[d]thiazole (373 mg, 2.2 mmol) and DIEA (452 μL, 2.64 mmol) wre poured into DMF (2.2 mL) and the resulting solution was heated two days at 120° C. The solvent was removed under reduce pressure and the crude product was purified over silicagel chromatography (prepacked 25 g silicagel column, Cyclohexane/AcOEt:70/30 as eluent) to afford 582 mg of N-(4-(pyridin-2-yl)but-3-ynyl)benzo[d]thiazol-2-amine (Yield: 95%) as a brownish oil.
