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-2HCl (70.6 mg, 0.209 mmol), (2-methylphenyl)acetic acid (31.4 mg, 0.209 mmol), HATU (79 mg, 0.209 mmol) in DMF (2 mL) was added Hunig's base (0.146 mL, 0.836 mmol). The mixture was stirred at room temperature overnight. LCMS showed reaction was completed. The reaction was poured into water (100 mL), white solid formed. EtOAc (100 mL) was used to extract the product. The Organic phase was separated from the water phase, dried by MgSO4, rotavaped to dryness, to give white solid. The solid was sonacated in water (10 mL), then filtered and dried to afford 7-methyl-5-{1-[(2-methylphenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7H-pyrrolo[2,3-d]pyrimidin-4-amine (48 mg) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.02-8.24 (m, 2H) 7.32 (s, 1H) 7.25 (s, 1H) 7.12-7.24 (m, 5H) 6.07 (br. s., 2H) 4.26 (t, J=8.5 Hz, 2H) 3.87 (s, 2H) 3.73 (s, 3H) 3.24 (t, J=8.5 Hz, 2H) 2.24 (s, 3H).
