Reaction Steps
p-Methoxyaniline (0.250 g, 2.03 mmol), triethylamine (0.206 g, 2.03 mmol) and 2-chloro-1,3-dimethylimidazolinium chloride (0.344 g, 2.03 mmol) were added to a methylene chloride solution (40 ml) of 5-(3,4,5,6-tetramethoxy-2-methylbenzyl)-2-benzyloxybenzoic acid (0.460 g, 1.02 mmol) and the resulting solution was stirred at room temperature for 12 hours. The reaction solution was poured into ice water and then extracted with methylene chloride. The extract was washed with water and then dried, and the solvent was removed by distillation. The obtained residue was purified by preparative thin-layer chromatography (ethyl acetate:hexane=1:2) and recrystallized from ether to obtain the titled compound (0.211 g, 0.379 mmol, 37%).
