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), (1-methyl-1H-pyrrol-2-yl)acetic acid (39.1 mg, 0.281 mmol), HATU (107 mg, 0.281 mmol), and DIEA (0.245 mL, 1.404 mmol) was stirred at room temperature for 3 days. The resulting suspension was poured into water (10 mL) and stirred for 30 min, and a precipitate formed. The precipitate was collected by filtration, and the residue was washed with water, then dried at the pump for an hour, then adsorbed onto silica and purified by flash chromatography (0-10% MeOH in EtOAc) to afford 5-{4-fluoro-1-[(1-methyl-1H-pyrrol-2-yl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (70 mg, 61.7% yield) as an off-white solid. LC-MS (ES) m/z=405 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ ppm 3.25 (t, J=8.34 Hz, 2H), 3.54 (s, 3H), 3.69-3.79 (m, 3H), 3.87 (s, 2H), 4.33 (t, J=8.34 Hz, 2H), 5.82-5.95 (m, 2H), 5.95-6.19 (m, 2H), 6.69 (t, J=2.27 Hz, 1H), 7.16-7.24 (m, 1H), 7.26 (s, 1H), 7.93 (d, J=8.08 Hz, 1H), 8.15 (s, 1H).
