Reaction Steps
The mixture of 10.3 g. of the compound obtained in (1), 8.2 g. of benzyl chloride, 10.2 g. of potassium carbonate, 0.5 g. of potassium iodide, and 100 ml of acetone was refluxed for 2 hours. The mixture was then filtered, and the filtrate was concentrated. Ether was added to the concentrate. The ether layer was washed successively with water, 1 N aqueous sodium hydroxide, and again with water. The solution was dried over magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was recrystallized from ethyl acetate/n-hexane, to obtain 12.2 g. (yield: 82.4%) of the subject compound.
