4,4-Difluoro-2,3,4,5-tetrahydro-1H-1-benzazepine derivatives represented by the following formula (I) or salts thereof:
(wherein each of the symbols has the following meaning:
ring A: a 5-membered heteroarylene group;
ring B: an optionally substituted aryl group or a 5- to 6-membered heteroaryl group;
D: a carbonyl group or a lower alkylene group;
R1: a group represented by formula, NR3R4, an -O-lower alkyl group, or OH;
R2: an optionally halogen atom-substituted lower alkyl group, an -O-lower alkyl group, an -S-lower alkyl group, or a -CO-lower alkyl group;
R3, R4: same or different and each is
1) a hydrogen atom,
2) a lower alkyl group (the lower alkyl group may be substituted with OH, an optionally protected amino group, an optionally protected mono-lower alkylamino group, a di-lower alkylamino group, an optionally lower alkyl group-substituted 5- to 7-membered saturated heterocyclic group, a 5- to 6-membered heteroaryl group, or an aryl group),
3) a cycloalkyl group,
4) an optionally lower alkyl group-substituted 5- to 7-membered saturated heterocyclic group,
5) a 5- to 6-membered heteroaryl group,
6) an aryl group, or
7) an optionally substituted 5- to 7-membered nitrogen-containing heterocyclic group formed by integration of the formula, NR3R4 (the 5- to 7-membered nitrogen-containing heterocyclic group may be fused with a benzene ring or with a 5- to 6-membered heteroaryl group); (in the 5- to 7-membered saturated heterocyclic group, the 5-to 7-membered nitrogen-containing heterocyclic group and the 5- to 6-membered heteroaryl group in the above 2), 4), 5) and 7), a group having a cyclic secondary amine may be one wherein the amine is protected); and
n: 0, 1 or 2.)
The compounds of the present invention exhibit the oxytocin antagonism and are effective in inhibiting threatened premature birth or abortion, or precesarean birth and useful as remedies for dysmenorrhea and so.
