실험 절차

A solution of (5)-3,5-dichloro-4-(2-(3,4-dimethoxyphenyl)-2-hydroxyethyl)-pyridine 1-oxide (0.688 g, 2 mmol), 3-formylbenzoic acid (0.300 g, 2 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.767 g, 4 mmol) and 4-(dimethylamino)pyridine (0.122 g, 1 mmol) in anhydrous DCM (30 mL) was stirred at RT for 21 hours. The reaction mixture was partitioned between saturated NaHCO3 (20 mL) and DCM (10 mL) and filtered through a phase separator cartridge. The cartridge was washed thoroughly with DCM and the solvent was removed in vacuo. The crude material was purified by silica gel column chromatography eluting with 1:1 DCM:EtOAc to afford the title compound as an off-white solid (0.863 g, 91%).
