Ethyl acetate was added to the reaction solution and the mixture was washed with water and brine and then dried over anhydrous magnesium sulfate. The solvent was evaporated and the residue was crystallized from ethyl acetate-hexane to give N-(3-benzylamino-1,4-dihydro-1,4-dioxo-2-naphthalenyl)-N-(2-methoxyethyl)acetamide (0.51 g) as a red powder.
