Versuchsvorschrift
N-(1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)-acetamide (16.5 g, 81 mmol) was added to 3N aqueous hydrochloric acid (270 ml) and stirred at 100° C. for 5 hours. After removal of the solvent, the precipitate was filtered, washed with ethanol, and dried to give 2-amino-3,4-dihydro-2H-naphthalen-1-one hydrochloride (16.0 g, 81 mmol, 100%) as white crystals.
