Versuchsvorschrift

To a solution of Compound 1 (5.0 g, 7.99 mmol) obtained in Example 1 in 50 ml of N,N-dimethylformamide was portionwise added sodium hydride (60%. in oil, 351 mg, 8.78 mmol) with stirring at room temperature, and 1-bromo-3-chloropropane (0.87 ml, 8.78 mmol) was added thereto, followed by stirring at room temperature for 4 hours. 1-Bromo-3-chloropropane (0.16 ml, 1.62 mmol) was added thereto and the mixture was stirred further for 4.5 hours. The reaction mixture was neutralized with a saturated aqueous solution of ammonium chloride, and water was added thereto followed by extraction with ethyl acetate. The resulting organic layer was washed with water and a saturated aqueous solution of sodium chloride and dried over magnesium sulfate, and the solvent was distilled off under reduced pressure to give 6.5 g of a crude product. The obtained crude product was purified with silica gel column chromatography (ethyl acetate/hexane=1/3-1/1) to give 5.35 g (yield: 95%) of the title compound.
