실험 절차

WSCD (822 mg, 4.3 mmol) and DMAP (273 mg, 2.2 mmol) were added to a solution of 4-(4-methoxycarbonyl-butyl)-3-methyl-benzoic acid from Example E31 (571 mg, 2.3 mmol) and 3-methyl-3,4,9,10-tetrahydro-2,3,4,9-tetraaza-benzo[f]azulene from Example E11 (424 mg, 2.1 mmol) in dichloromethane (50 ml) and triethylamine (0.6 ml, 4.3 mmol). The mixture was heated at reflux for 72 h, diluted with dichloromethane, washed with 0.3M KHSO4, saturated NaHCO3 then brine, dried and concentrated in vacuo. The residue was purified by flash chromatography on silica gel (eluant; EtOAc to 5% triethyamine: 95% EtOAc) to yield the title compound (424 mg, 46%).
