Reaction Steps
5,6-Dichloro-7-methoxy-1-tetralone (20 g., 0.08 mole) dissolved in acetic acid (300 ml.) is hydrogenated over 5% palladium on carbon (12 g.). The catalyst is removed and washed well with acetic acid. The combined acetic acid fractions are evaporated to dryness and the residue is crystallized from hexane to obtain 5,6-dichloro-7-methoxytetralin (17 g.), melting point 67°-68.5° C.
