Synthesis of the trifluromethylated retinoial aromatic amide-4-[1-(5,6,7,8-tetrahydro-3-trifluoromethyl-5,5,8,8-tetramethyl-2-naphthalenyl)carbamoyl]benzoic acid.
A new methodology was developed for the preparation of an o-trifluoromethylated arylamine. The condensation of 2-amino-3-trifluoromethyl-5,6,7,8-tetrahydro-5,5,8,8-tetramethylnaphthalene and terephthalic acid monomethyl ester chloride gave the trifluoromethylated retinoial aromatic amide. The key step in the synthesis is the introduction of the aryl trifluoromethyl group.
