Versuchsvorschrift

A mixture of benzoyl chloride (50 mL), cyclohexanediol (150 g), pyridine (105 mL) and tetrahydrofuran (1300 mL) was stirred at room temperature overnight. The reaction mixture was concentrated under reduced pressure, the residue was diluted with ethyl acetate, successively washed with saturated aqueous sodium hydrogen carbonate, water, and brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound as a colorless oil (81.5 g, 86%).
