Procedure

A mixture of 4-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)benzaldehyde (0.400 g, 1.09 mmol), N1-[2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-2-fluoro-4-(trifluoromethyl)benzamide (0.735 g, 1.20 mmol), palladium tetrakis(triphenylphosphine) (0.127 g, 0.110 mmol), and sodium carbonate (0.279 g, 2.63 mmol) in DME (10 mL) and water (10 mL) was heated at 85° C. for 1 h. Additional N1-[2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-2-fluoro-4-(trifluoromethyl)benzamide (0.026 g, 0.059 mmol) was added and the reaction mixture was heated at 85° C. for 4 h. The reaction mixture was cooled to ambient temperature and filtered. The residual solid was washed with methanol (50 mL) and DMF (50 mL), and the combined filtrates were concentrated to afford N1-{4-[4-amino-1-(4-formylphenyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-2-fluoro-4-(trifluoromethyl)benzamide as a beige solid (0.402 g, 0.730 mmol): 1H NMR (d6-DMSO, 400 MHz): δH 10.05 (1H, s), 9.96 (1H, d, J=4.0 Hz), 8.62 (1H, d, J=8.4 Hz), 8.46 (1H, s), 8.39 (1H, d, J=6.8 Hz), 8.12 (2H, d, J=8.8 Hz), 8.02-8.03 (1H, m), 7.84-8.00 (1H, m), 7.75-7.77 (1H, m), 7.51 (1H, s), 7.43 (1H, d, J=8.0 Hz), 3.97 (3H, s); RP-HPLC (Hypersil C18, 5 μm, 100 Å, 15 cm; 5%-100% acetonitrile-0.1 M ammonium acetate over 15 min, 1 mL/min). Rt 12.46 min. MS: MH+ 551.2.
