Procedure

A solution of 3-(2,3-dihydro-1H-indol-5-yl)-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (89 mg, 0.293 mmol), (3,5-dichlorophenyl)acetic acid (60 mg, 0.293 mmol), HATU (111 mg, 0.293 mmol), DIEA (0.204 mL, 1.171 mmol) was stirred at room temperature overnight. The crude was poured into water and stirred for 30 minutes. The precipitate that formed was collected by filtration, washed with water and dried at the pump for 30 minutes. The crude was adsorbed onto silica and purified by flash chromatography (0-10% methanol in DCM), concentrated and dried overnight in a vacuum oven to afford 3-{1-[(3,5-dichlorophenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (80 mg) as a white solid. LCMS (ES) m/z=453, 455 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 3.29 (t, J=9.60 Hz, 2H), 3.94 (s, 3H), 3.97 (s, 2H), 4.26 (t, J=8.59 Hz, 2H), 7.40 (d, J=2.02 Hz, 2H), 7.45 (d, J=8.08 Hz, 1H), 7.53 (d, J=1.77 Hz, 2H), 8.17 (d, J=8.34 Hz, 1H), 8.25 (s, 1H).
