Reaction Steps

N-[5-(3,4,5,6-Tetramethoxy-2-methylbenzyl)-2-hydroxybenzoyl]piperidine (0.150 g, 0.350 mmol) was dissolved in methylene chloride (3.5 ml) and after adding thereto in sequence copper acetate (0.064 g, 0.350 mmol), 4-pyridylboronic acid (0.086 g, 0.700 mmol), Molecular Sieves 4A (0.150 g), triethylamine (0.088 g, 0.874 mmol) and pyridine (0.069 g, 0.874 mmol), the solution was stirred at room temperature for 12 hours. The reaction solution was filtered and the filtrate was poured into water and then extracted with methylene chloride. The extract was washed with saturated brine, then dried and concentrated. The obtained residue was purified by silica gel column chromatography (chloroform:methanol=9:1) to obtain the titled compound (0.055 g, 0.109 mmol, 31%).
