Ethyl Acetate → HCID 10721431, compound

Participants

Reaction Steps

To a solution in DMSO (20 mL) of 4,4-bis(4-(2-quinolylmethoxy)phenyl)-pentan-1-ol (410 mg, 0.74 mmol), prepared as in Example 4, and 1,3-dicyclo-hexylcarbodiimnide (515 mg, 2.5 mmol) was added aqueous IM phosophoric acid (0.5 mL) and the resulting mixture was stirred at room temperature for 4 hours. Ethyl acetate (80 mL) was added and dicyclohexylurea was filtered off. The filtrate was washed with water and brine dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by chromatography on silica gel (methylene chloride-ethyl acetate 9:1) to afford 280 mg of 4,4-bis(4-(2-quinolylmethoxy)phenyl)pentanal.
