Procedure

p-Methoxyaniline (0.078 g, 0.639 mmol), triethylamine (0.066 g, 0.639 mmol) and 2-chloro-1,3-dimethylimidazolinium chloride (0.108 g, 0.639 mmol) were added to a methylene chloride solution (20 ml) of 5-(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-(3-pyridylmethyloxy)benzoic acid (0.135 g, 0.318 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 (chloroform:methanol=9:1) and then recrystallized from ether to obtain the titled compound (0.040 g, 0.0756 mmol, 24%).
