Reaction Steps

1H-pyrazolo[3,4-d]pyrimidin-4-amine (1 equivalent), N-iodosuccinimide (1.25 equivalents) and AIBN (0.1 equivalents) are heated in acetonitrile for 10 h. The reaction is filtered and the filtered material (1 equivalent) is placed in DMF. Pd(dppf)Cl2 (0.6 equivalents), KI (0.1 equivalents), K3PO4 (3 equivalents) and 2-((2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)methyl)pyridine (1 equivalent) are added and the mixture is heated at 80° C. overnight. The reaction is partitioned between EtOAc and water, the organic layer is separated, washed with water, brine, dried over Na2SO4 and filtered. The filtrate is concentrated under reduced pressure and purified by column chromatography.
