Reduction of 6-amino-2,3-dihydrobenzo[b]thiophen-1,1-dioxide with DIBAL-H gave 6-amino2,3-dihydrobenzo[b]thiophen from which the title azide was prepared; its photolysis in diethylamine-THF gave 7-diethylamino-2,3-dihydro-8H-thieno[2,3-d]azepine which was converted into 7-diethylamino-8H-thieno[2,3d]azepine.
用DIBAL-H还原6-氨基-2,3-二氢苯并[b]噻吩-1,1-二氧化物,得到6-氨基2,3-二氢苯并[b]噻吩,由其制备标题叠氮化物。其在二乙胺,THF光解,得到7-二乙基氨基-2,3-二氢-8H-噻吩并[ 2,3d ]吖庚因将其转化成7-二乙氨基8H -噻吩并[ 2,3d ]吖庚因。
