Cis-3-(4-imidazo[1,2-a]pyridin-2-ylphenyl)-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine was prepared from cis-3-iodo-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.200 g, 0.453 mmol) and 2-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]imidazo[1,2-a]pyridine (0.250 g, 0.679 mmol) in a manner similar to that used for the preparation of cis-N2-(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-2-fluorophenyl)-1,3-benzoxazol-2-amine. The compound was formed as a white powder (0.021 g, 9%). 1H NMR (DMSO-d6, 400 MHz) 1.57-1.73 (m, 4H), 2.08-2.50 (m, 12H), 2.16 (s, 3H), 3.37 (m, 1H), 4.82 (m, 1H), 6.92 (t, 1H), 7.27 (t, 1H), 7.61 (d, 1H), 7.74 (d, 2H), 8.15 (d, 2H), 8.24 (s, 1H), 8.56 (d, 1H); RP-HPLC Rt 8.16 min, 97% purity (5% to 85% acetonitrile/0.1M aqueous ammonium acetate, buffered to pH 4.5, over 20 min at 1 mL/min; λ=254 nm; Deltapak C18, 300 Å, 5 μm, 150×3.9 mm column); m/z 508 (MH+).
