Participants

Reaction Steps

Zinc powder (24 g, 367 mmol) was added to a solution of 3,4-dihydro-[1,2]naphthoquinone 2-oxime (21.5 g, 123 mmol) in acetic acid (200 mw) and acetic anhydride (150 ml), and the solution was stirred at room temperature for 12 hours. After filtration and removal of the solvents under reduced pressure, the residue was partitioned between water and chloroform. The organic layer was washed with brine and dried over anhydrous magnesium sulfate. After removal of the solvent, the residue was washed with ethyl acetate and dried to afford N-(1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)-acetamide (16.5 g, 81 mmol, 66%) as brown crystals.
