Process for the preparation of 3-hydroxy-2,4,5-trifluorobenzoic acid alkyl ester and / or 3-alkoxy-2,4,5-trifluorobenzoic acid alkyl ester

摘要

The present invention relates to a process for the preparation of alkyl 3-hydroxy-2,4,5-trifluorobenzoates and/or alkyl 3-alkoxy-2,4,5-trifluorobenzoates, by reacting 3-hydroxy-2,4,5-trifluorobenzoic acid with a dialkyl carbonate at 80 to 200 DEG C.
