Abstract

2-Hydroxypyrrolo [2, 1-c][1, 4] benzodiazepines were aromatised in refluxing thionyl chloride into 11-chloropyrrolo [2, 1-c][1, 4] benzodiazepines in high yield. This aromatic system is doubly reactive towards nucleophiles leading to rearranged products such as iminobenzoxazines and quinazolines.
