Claims13
A process for preparing a compound of formula (I)
- comprising
- first preparing a compound of formula (II)
- in a step a) by reacting a compound of formula (III) with glycidol (IV) to give a compound of formula (II)
- and
- converting said compound of formula (II) into a compound of formula (I), in a step b) by reacting the compound of formula (II) with an alcohol of formula (V) to give a compound of formula (I)
- where
- Rf is CF3—(CF2)0-3—O—,
- R is a linear or branched alkyl or siloxane group, optionally containing one or more heteroatoms, or a group Rf′, and
- Rf′ is a fluorinated, linear or branched alkyl group, optionally containing one or more heteroatoms.
