実験手順

To mixture of 17 g of m-bromomethylphenol in 150 ml of carbon tetrachloride under argon was added a solution of 25.5 g of phosphorous oxychloride in 25 ml of carbon tetrachloride. The solution was cooled in a water bath and a solution of 9.18 g of triethylamine in 35 ml of carbon tetrachloride was added dropwise with stirring over 40 minutes. This mixture was stirred in the water bath for 1 hour then overnight at room temperature, filtered through diatomaceous earth and washed with carbon tetrachloride. The mother liquor was taken to dryness giving 23-29 g of the desired compound as a pale yellow oil.
