Reaction Steps

In a 20 mL vial with cap, to the solution of 3-(2,3-dihydro-1H-indol-5-yl)-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine-2HCl (70 mg, 0.206 mmol), (3-fluorophenyl)acetic acid (31.8 mg, 0.206 mmol), HATU (78 mg, 0.206 mmol) in DMF (2 mL) was added Hunig's base (0.144 mL, 0.825 mmol). The mixture was stirred at rt for overnight. LCMS showed reaction was completed. The reaction was poured into water, white solid formed. The white solid was filtered to give the product. LC/MS (ES) m/z=403.2 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ ppm 3.26 (t, J=8.46 Hz, 2H), 3.93 (s, 5H), 4.25 (t, J=8.46 Hz, 2H), 7.11 (s, 1H), 7.13-7.17 (m, 2H), 7.39 (d, J=6.82 Hz, 1H), 7.44 (d, J=8.34 Hz, 1H), 7.51 (s, 1H), 8.18 (d, J=8.34 Hz, 1H), 8.25 (s, 1H).
