Procedure

Nitrogen was bubbled into a mixture of 1-cyclobutyl-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-ylamine (60.0 mg, 0.190 mmol), 2-phenyl-7-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-quinoline (64.4 mg, 0.194 mmol), Na2CO3 (50.5 mg, 0.476 mmol), and Pd(PPh3)4 (13.7 mg, 0.0119 mmol) in DMF (4 mL)/water (1 mL) for 5 min, then the mixture was heated under nitrogen to 80° C. (bath temp.) for 17 h. The solvents were evaporated, water was added, the mixture was extracted with CH2Cl2 (3×20 mL), and the combined extracts were washed with brine and dried over MgSO4. MgSO4 was filtered off, and the filtrate was concentrated and chromatographed on an SCX column (1 g/6 mL barrel). The amine-containing fraction was adsorbed onto Hydromatrix and chromatographed on silica gel [Jones Flashmaster, 5 g/25 mL cartridge, eluting with CH2Cl2 (1-11)→1% MeOH in CH2Cl2 (12-28)→2% MeOH in CH2Cl2 (29-46)], yielding the title compound as off-white solid. 1H NMR (CDCl3, 400 MHz): δ=1.87-2.04 (m, 2H), 2.48-2.58 (mc, 2H), 2.86-2.98 (mc, 2H), 5.50 (quint, J=8.0 Hz, 1H), 5.57 (brs, 2H), 7.47-7.52 (m, 1H), 7.53-7.58 (m, 2H), 7.96 (dd, J=1.6, 8.3 Hz, 1H), 7.97 (d, J=8.6 Hz, 1H), 8.02 (d, J=8.0 Hz, 1H), 8.19-8.23 (m, 2H), 8.31 (d, J=8.6 Hz, 1H), 8.42 (s, 1H), 8.49-8.52 (m, 1H). 13C NMR (CDCl3, 100.6 MHz, DEPT135): δ=14.99 (−), 29.91 (2C, −), 50.61 (+), 98.68 (Cquart), 119.59 (+), 126.53 (+), 126.97 (Cquart), 127.56 (2C, +), 128.66 (+), 128.79 (2C, +), 129.00 (+), 129.53 (+), 134.83 (Cquart), 136.53 (+), 139.14 (Cquart), 143.40 (Cquart), 148.22 (Cquart), 154.00 (Cquart), 155.53 (+), 157.92 (Cquart), 158.18 (Cquart). MS (ES+): m/z 393.1 (53) [MH+]. HPLC: tR=3.1 min (OpenLynx, nonpolar—5 min), 3.6 min (OpenLynx, polar—5 min).
