2,7-Diazapyrene is synthesized in three high-yield steps from commercially available 1,4,5,8-naphthalene tetracarboxylic dianhydride, which first reacts with concentrated ammonium hydroxide solution at room temperature to give 1,4,5,8-naphthalenetetracarboxylic diimide (96%). The latter compound is subsequently reduced with borane in refluxing tetrahydrofuran to give 1,2,3,6,7,8-hexahydro-2,7-diazapyrene
由三个市售的1,4,5,8-萘四甲酸二酐以三个高收率的步骤合成2,7-二氮杂yr烯,该化合物首先与浓氢氧化铵溶液在室温下反应,得到1,4,5,8-萘四甲酸二酰亚胺(96%)。后一化合物随后在回流四氢呋喃中用硼烷还原,得到1,2,3,6,7,8-六氢-2,7-二氮杂py(77%),其随后在回流苯中用二氧化锰氧化,得到2 ,7-二氮杂re(71%)。
