Reaction Steps

5-(3,4,5,6-Tetramethoxy-2-methylbenzyl)-2-(3-pyridyl)benzoic acid (80 mg, 0.1886 mmol), 4-dimethylaminopyridine (12 mg, 0.0983 mmol) and piperidine (32 mg, 0.3764 mmol) were dissolved in methylene chloride (10 ml), WSC-HCl (109 mg, 0.5685 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 (methylene chloride:methanol=95:5) to give the title compound (45 mg, 0.0918 mmol, 49%).
