Versuchsvorschrift

For example, 6-hydroxynaphthalene-2-carboxylic acid in a solvent such as tetrahydrofuran is reduced with hydrogen gas in the presence of a reducing catalyst such as a palladium/carbon under elevated pressure to obtain 5,6,7,8-tetrahydro-6-hydroxynaphthalene-2-carboxylic acid (1).
