Patent ID: 8754079

Claim:
A compound of Formula (I) wherein X is CH or N, R 1 is a hydrogen or halogen atom, R 2 is C 3-7 cycloalkyl group that is substituted with one or two substituents selected from oxo, halogen, C 1-3 alkyl, hydroxy, C 1-3 alkoxy, C 1-4 alkoxy-carbonyl, amino and morpholinyl, wherein the hydrogen atoms of the amino group may optionally be independently replaced by a C 1-3 alkyl, C 1-3 alkoxy-(CH 2 ) m —, C 1-4 alkoxy-carbonyl, C 1-3 alkylsulfonyl, C 1-3 alkyl-carbonyl, C 3-6 -cycloalkyl-carbonyl or piperidinyl group, wherein m is 2 or 3 and wherein the piperidinyl group may optionally be substituted by a methyl group, wherein two substituents, which are attached to the same carbon atom, together may form a —O—(CH 2 ) 2 —O— group, and wherein two substituents, which are attached to two adjacent carbon atoms, together may form a —O—CH 2 —O— or —O—C(CH 3 ) 2 —O— group, R 3 is a C 1-2 alkyl group and R 4 is a carboxy, C 1-3 alkoxy-carbonyl, aminocarbonyl, N—(C 1-4 alkyl)-aminocarbonyl or N,N-[di(C 1-4 alkyl)]-aminocarbonyl group, wherein the aminocarbonyl group may be substituted with a C 1-3 alkylsulfonyl, CN, OH, C 1-3 alkoxy, C 3-6 cycloalkyl, —CH 2 —C≡C—CH 2 —NH 2 , —CH 2 —C—CH 2 —NH(C 1-3 alkyl) or —CH 2 —C≡C—CH 2 —N(C 1-3 alkyl) 2 group or with a piperidinyl or pyrrolidinyl group bound via a carbon atom, and wherein the alkyl moieties of the above-mentioned N—(C 1-4 alkyl)-amino-carbonyl and N,N-[di-(C 1-4 alkyl)]-aminocarbonyl groups may optionally be substituted with an aminocarbonyl, N—(C 1-3 alkyl)-aminocarbonyl or N,N-[di-(C 1-3 alkyl)]-aminocarbonyl group or with a pyrrolidinyl, oxazolyl, imidazolyl, piperidinyl or morpholinyl group, each bound via a carbon atom, or, if the alkyl moiety is a (C 2-4 alkyl), it may be substituted with a OH, CN, C 1-3 alkoxy, amino, N—(C 1-3 alkyl)-amino, N,N-[di-(C 1-3 alkyl)]-amino, C 1-5 alkyloxy-carbonyl-amino, morpholino, piperidino, piperazino, pyrrolidino, azetedinyl, aziridinyl or imidazolyl group, with the proviso that said (C 2-4 alkyl) moiety may not be substituted on the 1-position of the alkyl moiety, wherein each of the above-mentioned cycloalkyl, pyrrolidinyl, oxazolyl, piperidinyl, morpholinyl, piperazinyl and imidazolyl groups may be substituted with a methyl, amino, hydroxy group or C 1-3 alkoxy, or a pharmaceutically acceptable salt thereof.
