Reaction Steps

In a 20 mL vial with cap, to the solution of 5-(2,3-dihydro-1H-indol-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine HCl (200 mg, 0.663 mmol), (2,5-difluorophenyl)acetic acid (120 mg, 0.696 mmol), HATU (265 mg, 0.696 mmol) in DMF (5 mL) was added Hunig's base (0.463 mL, 2.65 mmol). The mixture was stirred at room temperature for overnight. LCMS showed reaction was completed. The reaction was poured into water, white solid formed. The solid was filtered and dried to afford 5-{1-[(2,5-difluorophenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine as a white solid. NMR showed there is 1 eq. of DMF in the compound. LCMS (ES) m/z=420 [M+H]+. 1H NMR (400 MHz, DMSO-d6) d ppm 3.27 (t, J=8.46 Hz, 2H), 3.74 (s, 3H), 3.95 (s, 2H), 4.29 (t, J=8.46 Hz, 2H), 6.05 (br. s., 2H), 7.21-7.27 (m, 5H), 7.34 (s, 1H), 8.09 (d, J=8.34 Hz, 1H), 8.15 (s, 1H).
