Versuchsvorschrift

A solution of 0.51 ml of methanesulfonyl chloride dissolved in 5 ml of benzene was added dropwise to a solution of 2.067 g of dl-7-(trans-3-hexadecyloxytetrahydropyran-2-ylmethoxy)-1-heptanol (prepared as described in Preparation 55) and 1.83 ml of triethylamine dissolved in 15 ml of benzene, whilst ice-cooling. The reaction mixture was stirred at room temperature for 15 minutes, after which it was washed with water, dried over anhydrous magnesium sulfate and concentrated by evaporation under reduced pressure, to give 2.406 g of crude dl-7-(trans-3-hexadecyloxytetrahydropyran-2-ylmethoxy)heptyl methanesulfonate as a viscous oil.
