6,11-Dihydro-5H-Pyrrolo[2,1-b][3]benzazepin-11-one and derivatives thereof are generally prepared by Friedel-Crafts ring closure of a N-phenethylpyrrole-2-carboxylic acid halide. They are useful intermediates in the synthesis of skeletal muscle relaxants and tranquilizers such as 11-(3-dimethylaminopropylidene)-6,11-dihydro-5H-pyrrolo[2,1-b][3]benzazepi ne.
6,11-Dihydro-5H-Pyrrolo[2,1-b][3]benzazepin-11-one和其衍生物通常通过对N-苯乙基吡咯-2-羧酸卤代物的Friedel-Crafts环合成法制备而成。它们是合成骨骼肌松弛剂和镇静剂(如11-(3-二甲基氨丙基亚甲基)-6,11-二氢-5H-吡咯[2,1-b][3]苯并[3]氮杂环烷)的有用中间体。
