実験手順

To a mixture of 2-[2-hydroxy-5-(2-methoxy-pyridin-3-yl)-phenyl]-3H-benzoimidazole-5-carboxylic acid (containing 1 equivalent of DMA, 145 mg, 0.33 mmol), NH4Cl (160 mg, 3.0 mmol) and HATU (141 mg, 0.37 mmol) in DMF (2 mL) was added DIEA (0.52 mL, 388 mg, 3.0 mmol). The reaction mixture was stirred at room temperature for 3 h and heated at 60° C. for 15 h, and then evaporated under reduced pressure. The residue was purified by chromatography (333:10:1 CH2Cl2/MeOH/28% aqueous NH4OH) to afford the title compound (29 mg, 24%). 1H NMR (DMSO-d6) δ 3.94 (s, 3H), 7.11-7.17 (2H), 7.36 (br s, 1H), 7.64 (d, J=9 Hz, 1H), 7.67 (d, J=9 Hz, 1H), 7.83-7.88 (2H), 8.05 (br s, 1H), 8.19-8.21 (2H), 8.30 (s, 1H). ESI-MS m/z 361.3 (MH+).
