反应详情

A mixture of Example 239 (41 mg, 0.1 mmol), 6-chloro-pyridin-3-ol (19 mg, 0.15 mmol), PPh3 (39 mg, 0.15 mmol), and di-tert-butyl azodicarboxylate (35 mg, 0.15 mmol) in THF (2 ml) was stirred at room temperature for 16 hours. The reaction mixture was diluted with MeOH/DMSO (1:1), and purified by preparative HPLC to provide the desired product. MS (ESI) m/e 517 (M+H)+; 1H NMR (499 MHz, DMSO-d6) δ 9.86 (s, 1H), 8.11 (d, J=3.12 Hz, 1H), 8.01 (d, J=8.42 Hz, 1H), 7.96 (s, 1H), 7.80 (d, J=8.11 Hz, 1H), 7.52 (s, 1H), 7.47 (m, 1H), 7.40 (d, J=8.73 Hz, 1H), 7.34 (m, 2H), 7.30 (dd, J=8.11, 1.56 Hz, 2H), 6.95 (m, 2H), 4.21 (t, J=6.55 Hz, 2H), 4.03 (s, 3H), 2.92 (t, J=6.55 Hz, 2H).
