実験手順
(Z)-N′-Hydroxy-4-(pyridin-3-yloxy)benzamidine (206 mg, 89.9 μmol), N-dimethylaminopyridine (1.1 mg, 9.0 μmol) and 4-benzyloxybenzoyl chloride (28.8 mg, 116.8 μmol) were suspended in pyridine (5.0 mL) and the solution was refluxed for 45 hours. The reaction mixture was then cooled to room temperature, the solvent was removed under reduced pressure and the solid residue was purified by column chromatography (EtOAc/Hex 1:4) to give the product as a white solid (30 mg, 78%). 1H NMR (500 MHz, CDCL3) δ(ppm): 5.16 (2H, s), 7.11 (2H, d, J=6.0 Hz), 7.12 (2H, d, J=6.2 Hz), 7.33-7.37 (2H, m), 7.39-7.46 (5H, m), 8.15 (2H, d, J=7.6 Hz), 8.17 (2H, d, J=7.4 Hz), 8.45 (1H, d, J=4.6 Hz), 8.49 (1H, d, J=2.4 Hz). 13C NMR (125 MHz, CDCL3) δ(ppm): 70.4 (CH2), 115.5 (CH), 117.2, 118.8 (CH), 123.0 (CH), 124.6, 126.8 (CH), 127.7 (CH), 128.5 (CH), 128.8, 128.9 (CH), 129.7 (CH), 130.3 (CH), 136.2, 141.9, 145.0, 159.1, 162.5, 168.3, 175.8. MS (FAB+): 422 (MH+). HRMS for C26H19N3O3 (MH+): calculated: 422.1505; found 422.1521.
