실험 절차
4-(Methoxycarbonyl)benzoic acid (4) (246 mg, 1.37 mmol) was dissolved in DCM (15 mL) and treated with EDC (654 mg, 3.41 mmol) and DMAP (33 mg, 273 μmol). The resultant mixture was stirred at RT for 15 min. 4-Ethoxy-3,5-bis(trifluoromethyl)aniline (3) (360 mg, 1.32 mmol) was added and the resultant mixture was stirred at RT for 20 h. The mixture was diluted with EtOAc and washed three times with 1 M HCl and then three times with NaHCO3 solution. The organic phase was washed with brine, dried over MgSO4, filtered and the solvent removed in vacuo. The residue was purified by silica gel chromatography (10% EtAOc in isohexane) to afford methyl 4-(4-ethoxy-3,5-bis(trifluoromethyl)phenylcarbamoyl)benzoate (5) (150 mg, 28%): m/z 436 [M+H]+ (ES+).
