Abstract
Abstract Compounds of formula ##STR1## wherein R 1 is hydrogen or one or more specified substituents, X is --O--or --NR 2 -- where R 2 is lower alkyl, lower alkenyl, lower alkynyl, aryl or specified substituted lower alkyl or R 2 represents a group --Z-- which is connected to the 8-position of the aromatic ring so as to form a heterocyclic ring of 5 to 7 ring members, Y is O or NR 3 where R 3 is hydrogen or lower alkyl, and B is a saturated azabicyclic ring (eg tropanyl or quinuclidinyl) or a N-oxide thereof and their acid addition salts are 5-HT 3 antagonists which may be used in, for example, the treatment of neuro-psychiatric disorders.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
146 words
A compound of the formula ##STR13## or a pharmaceutically acceptable acid addition salt thereof, in which R 1 represents hydrogen or one or more substituents selected from lower alkyl, hydroxy, lower alkoxy, halogen, methylenedioxy, halo(lower)alkyl, nitro, amino, (lower)alkylamino and di(lower)alkylamino; X represents a group of formula --Z-- which is connected to the 8-position of the aromatic ring so as to form a heterocyclic ring of 5-6 ring members wherein the ring members represented by Z are two or three methylene groups optionally substituted by one or more lower alkyl groups and the X position of the --Z-- chain is N; Y represents O or NR 3 where R 3 is hydrogen or lower alkyl and B represents a saturated azabicyclic ring, or an N-oxide thereof, wherein the saturated azabicyclic ring has the formula ##STR14## where m is 2 or 3 R 4 is hydrogen or (lower)alkyl.
Claim 2
Dependent Claim
146 words
A compound of the formula ##STR13## or a pharmaceutically acceptable acid addition salt thereof, in which R 1 represents hydrogen or one or more substituents selected from lower alkyl, hydroxy, lower alkoxy, halogen, methylenedioxy, halo(lower)alkyl, nitro, amino, (lower)alkylamino and di(lower)alkylamino; X represents a group of formula --Z-- which is connected to the 8-position of the aromatic ring so as to form a heterocyclic ring of 5-6 ring members wherein the ring members represented by Z are two or three methylene groups optionally substituted by one or more lower alkyl groups and the X position of the --Z-- chain is N; Y represents O or NR 3 where R 3 is hydrogen or lower alkyl and B represents a saturated azabicyclic ring, or an N-oxide thereof, wherein the saturated azabicyclic ring has the formula ##STR14## where m is 2 or 3 R 4 is hydrogen or (lower)alkyl.
Claim 3
Dependent Claim
16 words
