Versuchsvorschrift
A mixture of 1.00 g (0.0044 mol) of 4-(1-ethoxyethoxy)-3,3-difluoro-4-methyl-1-pentanol, 4 mL of pyridine and 1.27 g (0.0066 mol) of p-toluenesulfonyl chloride was stirred at 0° C. for 18 hr. The mixture was quenched with ice chips. The mixture was then poured into water and extracted with methylene chloride. The organic phase was sequentially washed with 10% aqueous sulfuric acid and saturated aqueous sodium bicarbonate solution. The organic phase was dried over anhydrous magnesium sulfate, filtered and evaporated to dryness to yield oily 4-(1-ethoxyethoxy)-3,3-difluoro-4-methyl-1-pentanol 1-(4-methylbenzenesulfonate).
