Versuchsvorschrift

A solution of 5-(2,3-dihydro-1H-indol-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine 2HCl (150 mg, 0.443 mmol), (3,5-difluorophenyl)acetic acid (76 mg, 0.443 mmol), HATU (169 mg, 0.443 mmol), DIEA (0.310 mL, 1.774 mmol) was stirred at room temperature overnight. LCMS indicated partial conversion, with a mixture of starting material, desired product and bis-acylated material, so the reaction mixture was poured into water (10 mL), and a precipitate formed. The precipitate was collected by filtration, and the residue was washed with water (10 mL), and dried at the pump for an hour. The beige solid was adsorbed onto silica, and purified by flash chromatography (0-10% methanol in DCM, 12-g column) to afford a pale yellow solid which showed presence of bis-acylated material. The product was adsorbed onto silica and purified by flash chromatography (100% EtOAc-10% MeOH in EtOAc, then 10% MeOH in DCM, 24-g column) to afford 5-{1-[(3,5-difluorophenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (92 mg, 49.5% yield) as a white solid. LC-MS (ES) m/z=420 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 3.21-3.28 (m, 2H), 3.74 (s, 3H), 3.95 (s, 2H), 4.24 (t, J=8.34 Hz, 2H), 6.04 (br. s., 2H), 7.06 (d, J=6.57 Hz, 2H), 7.14 (t, J=9.60 Hz, 1H), 7.21-7.29 (m, 2H), 7.33 (s, 1H), 8.07-8.21 (m, 2H).
