On the basis of earlier finding that an alkylsulfonyl group when introduced into simple benzene derivatives exerted a CNS activity, ethylsulfonyl derivatives of dibenzo [b, e]-[1, 4] diazepines (VII, VIII, and X) were synthesized. A dimethylsulfamyl derivative (XX) was also prepared for comparison. VII (R=CH3, n=2) was selected as a potent anti-depressant with low toxicity.
