Procedure

1-(3-iodobenzyl)-N-(1-methyl-1H-pyrazol-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-amine (80 mg, 0.185 mmol), was dissolved in dioxane (1.2 mL) and added to a microwave tube. A mixture of Cs2CO3 (150 mg, 0.462 mmol) and X-Phos ligand (dicyclohexyl(2′,4′,6′-triisopropyl-[1,1′-biphenyl]-2-yl)phosphine, 4.4 mg, 9.2 μmol) and morpholine (40 μL, 0.462 mmol) was then added to the stirred solution, followed by the catalyst Pd2(dba)3 (1.65 mg, 1.8 μmol). The solution was degassed for 5 minutes with nitrogen and the tube was sealed under Nitrogen. The tube was heated in the microwave oven for 1 h at 140° C. then the mixture was diluted with ethyl acetate and washed with water. The aqueous phase was extracted with ethyl acetate and the combined organics were washed with brine and dried over Na2SO4. The solution was then filtered and the solvent removed in vacuo to obtain a crude solid which was purified by flash chromatography (ethyl acetate 100% to ethyl acetate/MeOH=85:15) to give the title compound as a white solid (38 mg, 52% yield). 1H NMR (d6-DMSO) δ 9.83 (br s, 1H), 8.91 (s, 1H), 8.08-7.98 (m, 2H), 7.59 (s, 1H), 7.15 (t, 1H), 7.03 (s, 1H), 6.84 (dd, J=8.2, 2.1 Hz, 1H), 6.69 (d, J=6.1 Hz, 1H), 5.49 (s, 2H), 3.84 (s, 3H), 3.72-3.63 (m, 4H), 3.07-2.95 (m, 4H); LC-MS method B, (ES+) 391.0, RT=7.44 min.
