Diisopropylethylamine → HCID 71478904、化合物

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), (6-chloro-2-pyridinyl)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. The resulting suspension was poured into water (10 mL) and stirred for 30 min. The resulting precipitate was collected by filtration, and the residue was washed with water (10 mL), dried at the pump for ca. 1 hour. The solid residue was dissolved in acetone and adsorbed onto silica and purified by flash chromatography (0-10% MeOH in EtOAc) to afford 5-{1-[(6-chloro-2-pyridinyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (99.8 mg, 53.7% yield) as a beige solid. LC-MS (ES) m/z=419 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 3.25 (t, J=8.34 Hz, 2H), 3.74 (s, 3H), 4.08 (s, 2H), 4.27 (t, J=8.46 Hz, 2H), 5.92-6.22 (m, 2H), 7.20-7.28 (m, 2H), 7.33 (s, 1H), 7.38-7.46 (m, 2H), 7.87 (t, J=7.83 Hz, 1H), 8.10 (d, J=8.34 Hz, 1H), 8.15 (s, 1H).
