Procedure

0.48 g of 3-trifluoromethyl-1-heptanol was dissolved in 0.79 g of pyridine, and the solution was cooled with ice, followed by addition of 0.5 g of p-toluenesulfonyl chloride, stirring for 2 hours under cooling with ice and stirring for 2 hours at room temperature. After the reaction, the product was acidified with 2N-hydrochloric acid and extracted with methylene chloride. The resultant methylene chloride solution was washed with water and dried with magnesium sulfate, and the solvent was distilled off, whereby 3-trifluoromethylheptyl p-toluenesulfonate was obtained in an amount of 0.82 g (yield: 92%) and showed: [α]D23 +0.5, [α]D23 +2.2 (c 2, methylene chloride).
