実験手順

To a solution of [3-(4-bromophenyl)-1H-1,2,4-triazol-1-yl]methyl 2,2-dimethyl-propanoate (0.108 g, 0.32 mmol; IV-30), 3-formylphenyl boronic acid (0.099 g, 0.66 mmol), and PdCl2(dppf).CH2Cl2 (0.024 g, 0.029 mmol) was added 2M Na2CO3 (aq) (0.38 mL, 0.76 mmol). The mixture was subjected to microwave heating (135° C./50 min), cooled, and partitioned between EtOAc and water. The aqueous layer was extracted with EtOAc, combined organic extracts were dried over Na2SO4 and concentrated in vacuo. The residue was purified by flash chromatography (EtOAc/hexanes), affording the title compound as a colorless solid. 1H NMR (400 MHz, CDCl3) δ ppm 1.20 (s, 9 H), 6.10 (s, 2 H), 7.63 (t, J=7.69 Hz, 1 H), 7.73 (d, J=8.06 Hz, 2 H), 7.90 (dd, J=14.65, 7.57 Hz, 2 H), 8.15 (m, 1 H), 8.23 (d, J=8.30 Hz, 2 H), 8.39 (s, 1 H), 10.10 (s, 1 H).
