Reaction Steps

5-(5,6-Dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-phenylbenzoic acid (40 mg, 0.1020 mmol), 4-dimethylaminopyridine (6.2 mg, 0.0508 mmol) and piperidine (17 mg, 0.2000 mmol) were dissolved in methylene chloride (5 ml), then WSC-HCl (59 mg, 0.3077 mmol) was added thereto and the mixture was stirred at room temperature for 16 hours. The reaction solution was washed with water and dried and the solvent was evaporated therefrom. The residue was purified by preparative thin layer chromatography (hexane:ethyl acetate=2:1) to give the title compound (16 mg, 0.0348 mmol, 34%).
