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.
