Procedure

A solution of 5-(4-fluoro-2,3-dihydro-1H-indol-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine 2HCl (100 mg, 0.281 mmol), 2,5-difluorophenylacetic acid (48.3 mg, 0.281 mmol), HATU (107 mg, 0.281 mmol), and DIEA (0.196 mL, 1.123 mmol) was stirred at room temperature overnight. The reaction mixture was poured into water (10 mL) and a precipitate formed. The precipitate was collected by filtration, and dried at the pump for 1 hour. The residue was adsorbed onto silica and purified by flash chromatography (0-10% MeOH in EtAc) to afford 5-{1-[(2,5-difluorophenyl)acetyl]-4-fluoro-2,3-dihydro-1H-indol-5-yl}-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (44.2 mg, 36.0% yield) as a white solid. LC-MS (ES) m/z=438 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ ppm 3.23-3.29 (m, 2H), 3.75 (s, 3H), 3.97 (s, 2H), 4.36 (t, J=8.34 Hz, 2H), 5.78-6.19 (m, 2H), 7.13-7.32 (m, 5H), 7.89 (d, J=8.08 Hz, 1H), 8.15 (s, 1H).
