Claims22
A compound of the formula ##STR10## in which R is hydrogen or a lower alkyl group;
- and (a) the pyridinyl ring is attached at position 4;
- each X group is independently selected from halogen, (C.sub.1-4)alkyl, (C.sub.1-5)alkoxy, (C.sub.1-6)haloalkyl, (C.sub.1-2)alkoxycarbonyl, aminocarbonyl, (C.sub.1-4)alkylamino, di(C.sub.1-2)alkylamino, di(C.sub.1-2)alkylaminocarbonyl, di(C.sub.1-2)- alkylamino-N-oxide, (C.sub.1-2)alkylthio, (C.sub.1-2)alkylsulfonyl, pyridinyl, phenylthio, phenylsulfonyl, phenyl, or benzylamino in which the aromatic ring is in turn unsubstituted or substituted with 1 to 5 halogen atoms;
- each Y group is independently selected from halogen, (C.sub.1-2)alkyl, (C.sub.1-2)alkoxy, (C.sub.1-2)alkylthio, (C.sub.1-2)alkylsulfonyl, hydroxyl, or trihalomethyl;
- m is 0, 1 or 2;
- and n is 0 to 5;
- or
- (b) the pyridinyl ring is attached at position 3;
- X is chloro, methoxy, or an acetylmethylamino group;
- Y is halogen;
- m is 0 or 1;
- and n is 0 or 1.
