N-(氧杂戊环-2-基甲基)丙-2-胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2-Isocyanato-5-[3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-N,N-dimethyl-benzamide (125 mg, 0.22 mmol), N,N-diisopropylethylamine (0.06 mL, 0.34 mmol), isopropyl-(tetrahydro-furan-2-ylmethyl)-amine (315 mg, 2.2 mmol), and methylene chloride (3 ml) were combined and stirred at room temperature for 18 hours. The reaction was concentrated to dryness in vacuo. The crude material was dissolved in a solution of tetrahydrofuran (4 mL) and methanol (1 mL). To the mixture was added 0.2 mL 50% w/v aqueous potassium hydroxide and the combined mixture stirred for 30 minutes. The reaction was quenched with saturated sodium bicarbonate, and the mixture was extracted with methylene chloride. The organic layer was dried over sodium sulfate and concentrated to dryness in vacuo. The crude material was purified by preparative HPLC to give 15 mg (27 μmol, 12%) of 2-[3-isopropyl-3-(tetrahydro-furan-2-ylmethyl)-ureido]-5-[3-(2-methoxy-phenyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-N,N-dimethyl-benzamide. 1H-NMR (250 MHz, CDCl3) δ 11.90 (s, 1H), 8.52 (d, J=2.1 Hz, 1H), 8.14 (d, J=2.0 Hz, 1H), 7.83 (d, J=8.5 Hz, 1H), 7.72-7.52 (m, 4H), 7.30 (t, J=7.1 Hz, 1H), 7.13 (d, J=7.9 Hz, 1H), 7.05 (t, J=7.4 Hz, 1H); MS: m/z 556.4 (M+H+). The reaction was concentrated to dryness in vacuo The crude material was dissolved in a solution of tetrahydrofuran (4 mL) and methanol (1 mL) To the mixture was added 0.2 mL 50% the combined mixture stirred for 30 minutes The reaction was quenched with saturated sodium bicarbonate the mixture was extracted with methylene chloride The organic layer was dried over sodium sulfate concentrated to dryness in vacuo The crude material was purified by preparative HPLC
