Reaction Steps
3.45 g (16.4 mmol) of trifluoroacetic anhydride is added to 0.83 ml (14.6 mmol) of acetic acid at 0° C. while leaving the mixture to return to ambient temperature over 2 hours. The mixture is then cooled down to 0° C. and 1.95 g (11.0 mmol) of 2,6-diisopropylphenol is added dropwise. The reaction medium is maintained under stirring for 12 hours before being poured into ice-cooled water. After extraction with dichloromethane, the organic phase is washed with sodium chloride in a saturated aqueous solution before being dried over magnesium sulphate, filtered and concentrated under vacuum. A colourless oil is obtained with a yield of 86%. This product is sufficiently pure to be used directly in the following stage.
