Procedure

In a 20 mL vial with cap, to a solution of 3-(2,3-dihydro-1H-indol-5-yl)-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine HCl (70 mg, 0.231 mmol), (3-chloro-2,4-difluorophenyl)acetic acid (47.8 mg 0.231 mmol), and HATU (88 mg, 0.231 mmol) in DMF (2 mL) was added Hunig's base (0.162 mL, 0.925 mmol). The mixture was stirred overnight. The reaction was poured into water (100 mL), and an off-white solid was formed. The solid was filtered, washed with water (10 mL), and dried to afford the title compound as an off-white solid. LC-MS (ES) m/z=455.4 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ ppm 3.24-3.31 (m, 2H), 3.94 (s, 3H), 4.03 (s, 2H), 4.32 (t, J=8.46 Hz, 2H), 7.30-7.36 (m, 1H), 7.39-7.46 (m, 2H), 7.54 (s, 1H), 8.14 (d, J=8.34 Hz, 1H), 8.25 (s, 1H).
