Following the general procedure for the Suzuki coupling, 7-cyclopropylmethyl-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine (94.0 mg, 0.299 mmol) was reacted with 2-phenyl-7-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-quinoline (104 mg, 0.314 mmol), Na2CO3 (79.0 mg, 0.745 mmol) and Pd(PPh3)4 (21 mg, 0.018 mmol) in DMF (7.5 mL)/water (1.5 mL). The crude material was purified by an SCX column (2 g/6 mL barrel) followed by column chromatography on silica gel [Jones Flashmaster, 10 g/70 mL cartridge, eluting with CH2Cl2 (1-14)→1% MeOH in CH2Cl2 (15-34)→2% MeOH in CH2Cl2 (35-56)], yielding the title compound as an off-white yellow solid. 1H NMR (CDCl3, 400 MHz): δ=0.44-0.50 (m, 2H), 0.63-0.71 (m, 2H), 1.29-1.39 (m, 1H), 4.15 (d, J=7.2 Hz, 2H), 5.20 (brs, 2H), 7.29 (s, 1H), 7.46-7.52 (m, 1H), 7.52-7.58 (m, 2H), 7.71 (dd, J=1.8, 8.2 Hz, 1H), 7.91 (d, J=8.8 Hz, 1H), 7.93 (d, J=8.4 Hz, 1H), 8.17-8.22 (m, 2H), 8.27 (d, J=8.8 Hz, 1H), 8.29-8.32 (m, 1H), 8.36 (s, 1H). 13C NMR (CDCl3, 100.6 MHz, DEPT135): δ=4.05 (2C, −), 11.31 (+), 48.99 (−), 100.98 (Cquart), 115.67 (Cquart), 118.96 (+), 123.30 (+), 125.94 (Cquart), 127.46 (+), 127.55 (2C, +), 128.23 (+), 128.47 (+), 128.87 (2C, +), 129.50 (+), 136.50 (Cquart), 136.55 (+), 139.45 (Cquart), 148.52 (Cquart), 150.97 (Cquart), 152.04 (+), 156.99 (Cquart), 158.12 (Cquart). MS (ES+): m/z 392.1 (100) [MH+], 338.2 (22) [MH+—C4H6]. HPLC: tR=2.9 min (OpenLynx, polar—5 min).
