Reaction Steps

4-Chloro-6-(1H-indazol-4-yl)-1-methyl-1H-pyrazolo[3,4-b]pyridine 7 (80 mg, 0.28 mmol) and 3′-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)acetanilide (1.4 equiv.) were suspended in 2 ml acetonitrile. Sodium carbonate (3 equiv., 92 mg) and bis(triphenylphosphine)palladium(II) chloride (0.05 equiv.) were added as a solution in water (0.5 ml). The reaction mixture was heated in microwave at 130° C. for 20 min. Water was added to the mixture, and the precipitated product was filtered and purified by column chromatography to yield 112. NMR (CDCl3): 2.27 (3H, s), 4.33 (3H, s), 7.34 (1H, br), 7.52-7.68 (5H, m), 7.84 (1H, d), 7.85 (1H, s), 8.10 (1H, s), 8.26 (1H, s), 8.96 (1H, s). MS: MH+ 383.12 (100%)
