In order to obtained the six-membered ring compound and a thorough assignment of the spectra, and further to prove that the six-membered ring compound was formed from the hydrogen transfer, the compound N-butyl-4-(N-methylphenylamino)-5-amino- 1, 8-naphthalimide 6 was designed to obtained with N-butyl-4-bromo-5-amino-1, 8-naphthalimide and N-methyl phenylamine as the starting material. However it was difficult to obtain the desired product as the different solvent giving the different products except the desired product.

为了能够得到六元环化合物作为定标的物质及其确切的谱图分析结果，并且为了进一步证明由五元环产物通过氢转移得到六元环产物的正确性，设计用N-丁基4-溴-5-氨基-1，8-萘酰亚胺与N-甲基苯胺反应生成N-丁基-4--5-氨基-1，8-萘酰亚胺6，结果发现这种方法很难实现，选择不同的溶剂会生成不同的产物，却都不是目标产物。
