Abstract
The reaction of N-acetyl derivatives of N,N′-trimethylene- and N,N′-tetramethylene-o-phenylenediamines with ethylene oxide gave the corresponding N-(β-hydroxyethyl)-N′-acetyl derivatives, the cyclization of which in refluxing hydrobromic acid leads to benzo[f]-1,5-diazabicyclo[3.2.2]nonene and benzo[g]-1,6-diazabicyclo[4.2.2.]decene.
