Versuchsvorschrift

8.00 g (53.3 mol) of 3-tert-butylphenol and 5.93 g (58.6 mol) of triethylamine were dissolved in 80 mL of toluene followed by dropping in 6.71 g (58.6 mol) of methanesulfonyl chloride over the course of 10 minutes at 10° C. followed by stirring for 10 minutes at 25° C. and confirming the 3-tert-butylphenol to no longer be present by gas chromatography. The reaction liquid was placed in water and following separation of the organic layer, was washed three times with water, once with saturated aqueous NaHCO3 solution and once with saturated brine followed by drying with MgSO4, concentrating and purifying the resulting residue by vacuum distillation to obtain 10.7 g (yield: 88%) of 3-tert-butylphenyl methanesulfonate.
