Versuchsvorschrift

To a solution of 5-(4-chloro-2,3-dihydro-1H-indol-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine 2HCl (300 mg, 0.805 mmol), (6-methyl-2-pyridinyl)acetic acid TFA salt (213 mg, 0.805 mmol), HATU (306 mg, 0.805 mmol), in N,N-Dimethylformamide (DMF) (50 mL) under nitrogen at 0° C. was added DIEA (0.562 mL, 3.22 mmol). The reaction was stirred overnight at room temperature, then poured into water and stirred for one hour. A brown precipitate formed which was collected by filtration and washed with water. The solid was dissolved in ca. 25 mL chloroform, and purified by flash chromatography (0-100% EtOAc in chloroform→0-10% MeOH in EtOAc, 24-g column) to afford 5-{4-chloro-1-[(6-methyl-2-pyridinyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (144 mg) as a yellow solid. LC-MS (ES) m/z=433 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ ppm 2.45 (s, 3H), 3.24 (t, J=8.46 Hz, 2H), 3.74 (s, 3H), 4.00 (s, 2H), 4.35 (t, J=8.46 Hz, 2H), 5.69-6.08 (m, 2H), 7.16 (t, J=6.82 Hz, 2H), 7.20-7.25 (m, 2H), 7.66 (t, J=7.58 Hz, 1H), 8.03 (d, J=8.34 Hz, 1H), 8.13 (s, 1H).
