Reaction Steps

A solution of 3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (4.12 g, 0.016 mol) in N,N-dimethylformamide (50 mL) was reacted with 60% sodium hydride in oil (0.75 g, 0.019 mol) at ambient temperature. The mixture was stirred for 15 minutes, and 2-chloro-4-nitropyridine (3.00 g, 0.019 mol) was added. The mixture was heated at 100° C. for 18 hours. The mixture was cooled to room temperature and the precipitate was filtered, washing with N,N-dimethylformamide (20 mL), and then slurried in ethyl acetate (50 mL) for four hours. The solid was filtered and dried in vacuo to give 1-(2-chloro-4-pyridyl)-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (2.39 g, 0.009 mol) as a tan solid:
