実験手順

Compound 5 (25 mg, 0.13 mmol, 1.0 eq), 6-methoxypicolinic acid (23 mg, 0.15 mmol, 1.1 eq), 2-(1H-7-Azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (56 mg, 0.15 mmol, 1.1 eq) and DIEA (25.7 μL, 0.148 mmol, 1.10 eq) were dissolved in CH2Cl2 (1.5 mL) and stirred at rt overnight. Water was added and the layers separated. The organic layer was dried (MgSO4), filtered and concentrated in vacuo. Purification by flash chromatography on silica gel afforded 39 mg (90%) of the title compound as a yellow solid: 1H NMR (400 MHz, DMSO-d6) δ 10.26 (s, 1H), 8.41 (d, J=2.5 Hz, 1H), 8.38 (dd, J=4.4, 1.5 Hz, 1H), 7.92 (t, J=7.8 Hz, 1H), 7.70-7.69 (m, 2H), 7.65 (d, J=8.6 Hz, 1H), 7.48 (ddd, J=8.4, 2.7, 1.6 Hz, 1H), 7.45-7.39 (m, 2H), 7.08 (d, J=8.0 Hz, 1H), 6.84 (dd, J=8.1, 1.9 Hz, 1H), 4.04 (s, 3H); ES-MS [M+1]+: 322.2.
