11-Chloro-6,11-dihydrodibenzothiepin and its 2-methyl derivative VI were transformed via the 11-(4-(ethoxycarbonyl)-1-piperazinyl) compounds IVc and Vc to 11-(1-piperazinyl) compounds IVb and Vb.Their reactions with 1-(3-chloropropyl)-1,3-dihydro-2H-benzimidazol-2-one (II) afforded the title compounds IVa and IVb.Similar reactions and sequences in the series of 10,11-dihydro-5H-dibenzocycloheptene, 4,9-dihydrothieno-2-benzothiepin, and 10,11-dihydrodibenzothiepin led to further oxatomide (Ia) analogues IIIa and VIIa-XIa.In the test of passivecutaneous anaphylaxis in rats, compound VIIIa was more active than Ia, and IVa had similar activity like Ia.
