Potassium Iodide → 6-(3-Methoxypropoxy)indan-1-one

Participants

Reaction Conditions

Reaction Steps

To a solution of 6-hydroxyindan-1-one (1.48 g) in acetonitrile (30 mL) were added 4-methoxybutyl 4-methylbenzenesulfonate (2.93 g), potassium iodide (166 mg) and potassium carbonate (2.07 g), and the mixture was heated to stir at 80° C. for 5 hours. To the reaction mixture was added water under ice-cooling, and then the mixture was extracted with ethyl acetate. The organic layer was washed with saturated saline, dried over sodium sulfate, and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=7/3), and then triturated with n-hexane/isopropyl ether (2:1) to give 6-(3-methoxypropoxy)indan-1-one [REx(11-1)] (1.1 g) as a colorless powder.
