実験手順
To a solution of 42 g of phosphorous oxychloride in 110 ml of carbon tetrachloride was added dropwise with stirring a solution of 25 g of 2-bromo-1-propanol in 25 ml of carbon tetrachloride. This mixture was stirred overnight, then taken to dryness, evaporated twice from toluene and dried. The residue was distilled on a Kugelrohr 75° C., 0.05 mm, giving 26.1 g of the desired compound as a colorless oil.
