利用對位胺基苯酚和聚甲醛在酸中聚合時，並無法直接得到6-amino， 3-benzodioxin。6-amino，3-benzodioxin是由6-nitro，3-benzodioxin還原而得。當使 用鋁氫化鋰做為還原劑時，僅能分離出偶氮偶合的產物，若使用palladium在活 性炭上，並以環己烯做為氫之提供者6-nitro，3-benzodioxin可被還原成所預期的 6-amino，3-benzodioxin。
A directed condensation between para-aminophenol and paraformaldehyde would not produce thetitle compound, G'-amino-1, 3-benzodioxin. Therefore, it was converted from 6-nitro-l, 3benzodioxin by a reduction method. The lithium aluminum hydride reduction afforded two azocoupling products, and the palladium on charcoal and cyclohexene reduction yielded thecorresponding 6-amino product.
