Reaction Steps

To a solution of 4-(9-hydroxynonyl)-7-methoxy-3-methyl-3-(4-pyridyl)chroman (108 mg, 0.272 mmol) in methylene chloride (2 mL) were added under ice-cooling triethylamine (0.057 mL, 0.41 mmol) and methanesulfonyl chloride (0.032 ml, 0.41 mmol), which was then stirred for 30 minutes. After the reaction was completed, saturated aqueous NH4Cl solution was added, the resulting mixture was then extracted with methylene chloride and washed with saturated saline solution. The organic layer was dried over magnesium sulfate, and the solvent was removed under reduced pressure. The residue was subjected to silica gel column chromatography (n-hexane:ethyl acetate=1:1) to give 4-(9-methanesulfonyloxynonyl)-7-methoxy-3-methyl-3-(4-pyridyl)chroman (492 mg, yield 38%).
