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-propoxy-1-pentanol (36.8 g., 0.193 mole) is added dropwise with stirring during 40 minutes. The ice bath is replaced by a cool (20° C.) 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 2 N hydrochloric acid and water, and dried over sodium sulfate. The solvent is distilled in vacuo to leave the crude title compound as a yellow oil.
