Versuchsvorschrift

To 0.03 mol 2,2′-biphenyldimethanol was added 30 ml tetrahydrofuran and 0.09 mol pyridine, then added 0.075 mol benzoyl chloride with stirring. The reaction mixture was heated refluxing for 4 hours, cooled and added 20 ml saturated saline. The mixture was extracted with ethyl acetate, and extract was dried over anhydrous sodium sulfate. The solvent was removed. Column chromatography gave 2,2′-biphenyldimethanol dibenzoate as a colorless viscous liquid, and the yield was 93%.
