    摘要： Novel pyrrolo[2,1-c][1,4]benzodiazepine hybrids as well as processes for the preparation of novel pyrrolo[2,1-c][1,4]benzodiazepine hybrids are dislcosed. More particularly, present invention relates to a process for the preparation of novel pyrrolo[2,1-c][1,4]benzodiazepine hybrids as DNA sequence selective agents which are useful as potential antitumour agents. In particular, the present invention relates to a process for the preparation of new pyrrolo [2,1-c][1,4]benzodiazepine hybrids as potential antitumour agents. These compounds have the formula XIV shown below:
