Synthesis and Tranquilizing Effect of New Dibenzoxazepines and Pyridobenzoxazepines

Abstract

ASERIES of new 6,7,8,9-tetrahydrodibenz[ b,f][1,4]oxazepin-11(10H)-ones (3) was prepared by alkylation of salicylamides 1 with 2-chlorocyclohexanone followed by cyclodehydration of the resulting 2-cyclohexyloxybenzamides 2. New pyrido [2,3-b] [1,4]benzoxazepin-6(5H)-ones (8) were prepared by reacting salicoyl chlorides 4 or their corresponding acids 5 with 3-amino-2-chloropyridines 6 followed by treatment of the resulting amides 7 with sodium methoxide. Some of the new compounds were subjected to preliminary screened for their tranquilizing effect.
