실험 절차

A solution of 5-(2,3-dihydro-1H-indol-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine 2HCl (250 mg, 0.739 mmol), 5-(2,3-dihydro-1H-indol-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine.2HCl (250 mg, 0.739 mmol), HATU (281 mg, 0.739 mmol), DIEA (0.516 mL, 2.96 mmol) was stirred at room temperature overnight. The reaction mixture was poured into 20 mL water and stirred for 30 mins. The grey precipitate was filtered, washed with water (10 mL) and dried for an hour at the pump. The residue was adsorbed onto silica and purified by flash chromatography (0-10% MeOH in DCM, 24-g column) to afford 7-methyl-5-{1-[(1-methyl-1H-pyrrol-2-yl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7H-pyrrolo[2,3-d]pyrimidin-4-amine (128 mg, 44.8% yield) as a white solid. LC-MS (ES) m/z=387 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 3.23 (t, J=8.34 Hz, 2H), 3.54 (s, 3H), 3.73 (s, 3H), 3.86 (s, 2H), 4.25 (t, J=8.59 Hz, 2H), 5.84-5.94 (m, 2H), 5.94-6.32 (m, 2H), 6.68 (t, J=2.15 Hz, 1H), 7.14-7.29 (m, 2H), 7.31 (s, 1H), 8.08-8.20 (m, 2H). An additional crop of material was obtained from crystals observed in the filtrate after standing overnight. The liquid was filtered and the residue washed with water and dried at the pump to yield a second crop of 7-methyl-5-{1-[(1-methyl-1H-pyrrol-2-yl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7H-pyrrolo[2,3-d]pyrimidin-4-amine (65 mg, 22.76% yield) as a beige solid.
