Novel benzoxazocines of formula (I) ##STR1## and their pharmaceutically acceptable acid addition salts, wherein R.sup.1 represents hydrogen, or one or more halogen, trifluoromethyl, lower alkyl, lower alkoxy, nitro, amino acylamino, mono- or di- (lower)alkyl-amino or cyano substituents, R.sup.2, R.sup.3 and R.sup.4, which may be the same or different, each represent hydrogen or lower alkyl or R.sup.3 and R.sup.4 together represent --(CH.sub.2).sub.3 -- or --(CH.sub.2).sub.4 --, R.sup.5 represents hydrogen, lower alkyl, phenyl (lower)alkyl or cycloalkyl (lower)alkyl, and Ar is a phenyl radical optionally substituted by one or more halogen, trifluoromethyl, lower alkyl, lower alkoxy, nitro or amino groups exhibit activity on the central nervous system, particularly as antidepressants. The compounds can be prepared from novel alcohols of formula (II) ##STR2## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and Ar are as defined above and X is fluorine, chlorine or bromine.
