Abstract: Title compds. (I; Y,Z = H, C1-4alkyl, alkoxy, halogen, CF3; n,p = 1-3), useful as anti-inflammatory agent, were prepd. by esterification of II and III. Thus, 4.0 g PCl5 were added to 60 g 6,11-dihydro-11-oxodibenz b,e oxepine-2-acetic acid in 70 ml benzene while cooling and were stirred for 4hr. The reactant was melted in 30 ml CHCl3 and 70 ml of the mixt. was reacted with 2.2 g benzyl alcohol and 2.0 g triethylamine to give 6,11-dihydro-11-oxodibenz b,e, oxepine-2-acetate(m.p.: 82-84≦̸C).
