Procedure

Following the general procedure for the Suzuki coupling, 7-cyclobutyl-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine (142.5 mg, 0.4536 mmol) was reacted with 2-phenyl-7-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-quinoline (150.2 mg, 0.4533 mmol), Na2CO3 (120 mg, 1.13 mmol) and Pd(PPh3)4 (32 mg, 0.028 mmol) in DMF (10 mL)/water (2 mL). The crude material was purified by column chromatography on silica gel [Jones Flashmaster, 10 g/70 mL cartridge, eluting with CH2Cl2 (1-12)→1% MeOH in CH2Cl2 (13-37)→2% MeOH in CH2Cl2 (38-61)], yielding the title compound as a pale yellow solid. 1H NMR (CDCl3, 400 MHz): δ=1.88-2.00 (m, 2H), 2.44-2.56 (m, 2H), 2.56-2.65 (m, 2H), 5.27 (brs, 2H), 5.35 (quint, J=8.6 Hz, 1H), 7.35 (s, 1H), 7.46-7.51 (m, 1H), 7.52-7.58 (m, 2H), 7.70 (dd, J=1.8, 8.2 Hz, 1H), 7.91 (d, J=8.4 Hz, 1H), 7.93 (d, J=8.0 Hz, 1H), 8.17-8.22 (m, 2H), 8.26 (d, J=8.4 Hz, 1H), 8.28-8.31 (m, 1H), 8.36 (s, 1H). 13C NMR (CDCl3, 100.6 MHz, DEPT135): δ=15.03 (−), 31.11 (2C, +), 48.26 (+), 101.15 (Cquart), 115.99 (Cquart), 118.99 (+), 120.86 (+), 125.97 (Cquart), 127.42 (+), 127.55 (2C, +), 128.26 (+), 128.48 (+), 128.87 (2C, +), 129.52 (+), 136.49 (Cquart), 136.55 (+), 139.43 (Cquart), 148.52 (Cquart), 150.79 (Cquart), 151.97 (+), 156.97 (Cquart), 158.12 (Cquart). MS (ES+): m/z 392.1 (17) [MH+], 338.2 (22) [MH+-cyclobutene]. HPLC: tR=3.0 min (OpenLynx, polar—5 min).
