실험 절차

N-(2,6-Dichlorobenzoyl)-4-(2-formylphenyl)-L-phenylalanine methyl ester (51.7 mg) and (triphenylphosphoranylidene)acetic acid methyl ester (75.8 mg) were dissolved in anhydrous toluene (1 mL) and stirred at 80° C. under N2 for 18 h. The mixture was allowed to cool and purified by preparative TLC (silica gel) using hexanes/EtOAc (2:1) as eluent to give N-(2,6-dichlorobenzoyl)-4-[2-[2-(methoxycarbonyl)ethenyl]phenyl]-L-phenylalanine methyl ester (48.0 mg). ESMS: m/z 512 (MH+).
