NOVEL DIBENZ |b,e¨ OXEPIN DERIVATIVES

The invention provides dibenz[b,e]oxepin derivatives represented by general formula (I), wherein R and R each represent a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group, one of R and R is a group represented by general formula (II), [wherein R represents a hydrogen atom or a lower alkyl group, A represents a hydroxy group, -O(CH2)m-R (wherein m represents an integer of 1 to 6 and R represents a hydrogen atom, a lower alkyl group, a lower alkoxy group, a 5- or 6-membered cyclic amino group or a lower alkoxycarbonyl group), a 5- or 6-membered cyclic amino group, a di(lower alkyl)-amino group or -NH(CH2)n-R (wherein n represents an integer of 0 to 3, and R represents a hydrogen atom, a hydroxy group, a phenyl group, a thiazole group or a 5- or 6-membered cyclic amino group)] and the other represents a lower alkoxy group.
