rac-N2-{4-[4-Amino-1-(1-methyltetrahydro-1H-3-pyrrolyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]phenyl}-5,7-dimethyl-1,3-benzoxazol-2-amine was prepared from rac-3-iodo-1-(1-methyltetrahydro-1H-3-pyrrolyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.200 g, 0.581 mmol) and N2-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-5,7-dimethyl-1,3-benzoxazol-2-amine (0.265 g, 0.726 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 (0.062 g, 23%). 1H NMR (DMSO-d6, 400 MHz) 2.39 (s, 3H), 2.32-2.40 (m, 3H), 2.40 (s, 3H), 2.75-2.80 (m, 2H), 3.08 (t, 1H), 3.26 (s, 3H), 5.40 (m, 1H), 6.80 (s, 1H), 7.11 (s, 1H), 7.66 (d, 2H), 7.93 (d, 2H), 8.24 (s, 1H), 10.85 (s, 1H); RP-HPLC Rt 10.905 min, 96% 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 455 (MH+).
