The appropriate substituted carbonylazides I treated with warm acetic acid give the corresponding acetamide IV or the cyclic lactam VI . This is a convenient route to 10,11‐Dihydro‐5 H ‐pyrrolo[1,2‐ a ][1,4]‐benzodiazepin‐11‐one and 10,11‐Dihydro‐4 H ‐thieno[2,3‐ e ]pyrrolo[1,2‐ a ][1,4]diazepin‐10‐one.
