HCID 57096462-Fluoro-4-(trifluoromethyl)cinnamic acid

Procedure

5.12 g of (E)-2-Fluoro-4-(trifluoromethyl)cinnamic acid were synthesized as described for (E)-3-(4-(methanesulfonyloxy)phenyl)acrylic acid using 2-fluoro-4-trifluoromethylbenzaldehyde (commercially available from Aldrich) instead of methanesulfonic acid 4-formylphenyl ester.
