Versuchsvorschrift

4-(9-aminononyl)-7-methoxymethoxy-3-(4-methoxymethoxyphenyl)-3-methylchroman (82.3 mg, 0.17 mmol) was dissolved in 5 ml of methylenechloride under argon atmosphere, which was then cooled down to 0° C. 4,4,5,5,5-pentafluoropentylsulfonyl chloride (110.4 mg, 0.42 mmol) in 1 ml of methylene chloride and triethylamine (0.07 ml, 0.5 mmol) was added thereto, and the mixture was stirred at the same temperature for 30 minutes. The reaction was quenched with water, and extracted with chloroform. The organic layer was dried over anhydrous magnesium sulfate, and concentrated. The residue was subject to flash chromatography in silica gel (n-hexane:ethyl acetate=5:1) to give the title compound (81 mg, yield: 67%) as a colorless oil.
