The title compds. (I; R=H, C1-6, alkyl, C2-6 alkenyl, C2-6 alkynyl, C1-6 hydroxyalkyl, cycloalkyl, phenylalkyl, alkanoyl, phenoxyalkyl, benzoylalkyl; Y, Y' = H, Br, F, Cl, methoxy, methylthio, MeF3; n, n'=1, 2) were prepd. Thus, 10, 11-dihydro-11-oxospiro-[dibenz (b,f) oxepin-10,4'-piperidine in formic acid was refluxed for 2 hr, treated with 38% formaldehyde soln., and refluxed again for 16 hr with stirring to give 10,11-dihydro-1'-methyl-11-oxospiro ! -[dibenz(b,f)oxepin-10,4'-piperidine hydrobromide.
