Reaction Steps

To a solution of 4-(3,4,5,6-Tetramethoxy-2-methylbenzyl)-2-(3-pyridyl)benzoic acid (82 mg, 0.1933 mmol) in methylene chloride (10 ml) were added 4-trifluoromethylaniline (47 mg, 0.2919 mmol), triethylamine (39 mg, 0.3861 mmol) and 2-chloro-1,3-dimethylimidazolinium chloride (98 mg, 0.5798 mmol) followed by stirring 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 (58 mg, 0.1024 mmol, 53%).
