Participants

Reaction Steps

5-(3,4,5,6-Tetramethoxy-2-methylbenzyl)-2-(4-pyridyl)benzoic acid (100 mg, 0.2364 mmol) and 1-ethylpropylamine (66 mg, 0.7586 mmol) were dissolved in methylene chloride (5 ml), then 4-dimethylaminopyridine (6 mg, 0.0491 mmol) and WSC-HCl (146 mg, 0.7616 mmol) were added thereto and the mixture was stirred for 6 hours at room temperature. The reaction solution was washed with water and dried and the solvent was evaporated. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:5) to give N-[5-(3,4,5,6-tetramethoxy-2-methylbenzyl)-2-(4-pyridyl)benzoyl]-1-ethylpropylamine (63 mg, 0.1280 mmol, 54%).
