Versuchsvorschrift

To a solution of 46 g of phosphorus oxychloride in 110 ml of carbon tetrachloride was added with stirring 21 g of 1-bromo-2-propanol. The mixture was stirred overnight, the solvent removed and the residue evaporated twice from toluene at 35° C., then evaporated to dryness giving a dark oil. This oil was distilled on a Kugelrohr at 75° C., 0.3 mm giving 16.3 g of the desired compound as a white oil.
