Reaction Steps

The mixture of 2-tributylstannylthiazole (2.24 g, 6.00 mmol), 5-iodopyridin-3-ylamine (1.10 g, 5.00 mmol) and Pd(Ph3P)4 (580 mg, 0.5 mmol) in 50 mL toluene was degassed using Ar. The mixture was then stirred under Ar at 115° C. for 3 h. The mixture was concentrated and subjected to flash column (0 to 7% MeOH in DCM) to isolate 5-(thiazol-2-yl)pyridin-3-amine (740 mg, 84% yield).
