Procedimiento

16.6 g (50 mmol) of the 6-decyloxynaphthalene-2-carboxylic acid obtained in the first stage was heated under reflux at 130° C. for 7 hours in the presence of 250 cc of acetic acid and 86.5 g (0.5 mol) of 47% hydrobromic acid. To the reaction mixture was added distilled water, and then the resulting mixture was concentrated under reduced pressure to obtain 10.60 g (50 mmol) of 1,2,3,4-tetrahydro-6-hydroxynaphthalene-2-carboxylic acid.
