実験手順

A stirring solution of 100 mg (0.20 mmol) of [1-(Isopropyl-phenyl-carbamoylmethyl)-3-methyl-2,4-dioxo-5-phenyl-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-yl]-acetic acid, prepared as in Intermediate 7, 32 mg (0.30 mmol, 1.5 equiv) of 1,2-phenylene diamine, 187 mg (0.40 mmol, 2.0 equiv) of bromo-tris-pyrrolidino-phosphonium hexafluorophosphate (PyBroP), and 80 mg (0.60 mmol, 3.0 equiv) of diisopropylethylamine in 2 mL of DMF is heated at 50° C. for 48 h. The DMF is removed in vacuo and the residue is dissolved in 20 mL of EtOAc and extracted with 20 mL 1N HCl. The organic layer is dried (MgSO4) and the solvent removed in vacuo. The resulting oil is purified by silica gel flash column chromatography using dichloromethane/MeOH 20/1 as eluent followed by further purification via reverse phase MPLC using a C-18 column and 60% acetonitrile/40% H2O with 0.1% TFA as eluent followed by lyophilization to afford 30 mg of the title compound as a white amorphous solid: 1H NMR (CDCl3, 300 MHz) δ9.38 (s, 0.7H), 9.17 (s, 0.3H), 7.53-7.04 (m, 17H), 6.81 (d, 1H, J=4.7), 4.97 (m, 1H), 4.57 (d, 0.5H, J=16.6), 4.27 (s, br, 2H), 3.87 (d, 0.5H, J=16.6), 3.36 (d, 1H, J=15.6), 3.13 (d, 1H, J=15.6), 2.60 (d, 0.5H, J=15.3), 2.42 (d, 0.5H, J=15.3), 1.61 (s, 1H), 1.22 (s, 2H), 1.09 (m, 6H); low resolution MS (FAB)m/e 590 (MH+), 482.
