Reaction Steps

To a tap water cooled solution of 79 g of phosphorous oxychloride in 200 ml of carbon tetrachloride is added dropwise with stirring a solution of 50 g of 1-pentanol in 125 ml of carbon tetrachloride. The temperature rises to 30° C. and stirring is continued for 18 hours. The solvent is evaporated and the syrup evaporated with toluene several times. The residue is distilled rom a Kugelrohr still to give 108.7 g of the desired product as a colorless oil, B.P. 85°-90° C./0.3 mm.
