반응 단계

30 g. (0.15 mole) of 1,8-naphthalimide and 12.5 ml. of 37% aqueous formaldehyde (0.17 mole) are combined in 100 ml. of dimethylformamide and heated on a hot plate (90°-110°) until all the materials dissolve. The solution is then allowed to stand overnight at 25°. The resulting precipitate is filtered off, washed with water and recrystallized from dioxane. This material is dried overnight at 25° (0.1 mm.) to yield 26.4 g. of the titled compound which has an indistinct melting point.
