Procedure
A solution of p-toluenesulfonyl chloride (42.0 g., 0.22 mole) in pyridine (100 ml.) is cooled in an ice bath while 4-acetoxy-5-(4-fluorophenoxy)-1-pentanol (49.7 g., 0.193 mole) is added dropwise with stirring during 40 minutes. The ice bath is replaced by a cool (20°) water bath and stirring is continued for 2 hours. The mixture is then poured into 500 ml. of water. The oily product is taken up in ether, washed with 2N hydrochloric acid and water and dried over sodium sulfate. The solvent is distilled in vacuo to leave 73.5 g. (93%) of the crude title compound as a yellow oil.
