実験手順

A solution of 1,2-diethoxalylaminonaphthalene (10.8 g, 0.03 mol) in 150 ml of acetic acid was treated dropwise with nitric acid (1.24 ml, 0.03 mol, d 1.52) and stirred over night at room temperature. Then an additional amount of nitric acid (2.0 ml, d 1.52) was added dropwise and the mixture was stirred for 17 h at room temperature. The mixture was poured into 200 ml of ice/water and the resulting precipitate was isolated by filtration and washed with water, a small amount of cold ethanol and ether affording 3.3 g (27%) of pure product,
