Patent ID: 8883789

Claim:
A compound of formula I in which R 1 represents phenyl or pyridyl which latter two groups are optionally substituted with one to three groups selected independently of one another from halogen, cyano, nitro, amino, C 1-5 alkyl, C 3-6 cycloalkyl, —O—C 1-5 alkyl, —N(R 5 )(R 6 ) and —C(O)N(R 5 )(R 6 ) which latter five groups are optionally substituted with one or more fluorine atoms; R 2 represents a 6-14-membered aryl or 5-14-membered heteroaryl which latter two groups are optionally substituted with 1 to 4 groups selected from —OH, halogen, cyano, 4-9-membered heterocyclyl, C 6-10 aryl, 5-9 membered heteroaryl, C 1-5 alkyl, —C 1-5 alkyl-OH, —O—C 1-5 -alkyl, —O—C 1-5 alkyl-O—C 1-5 -alkyl, C 3-5 alkynyl, —C 1-5 alkyl-O—C 1-5 alkyl, C 3-7 cycloalkyl, —O—C 3-7 cycloalkyl, —O—CH 2 —C 3-7 cycloalkyl, C 1-5 alkyl-CO—, —C 1-5 alkyl-N(R 5 )(R 6 ), —N(R 5 )(R 6 ) and —S(O) 2 —C 1-5 alkyl which latter sixteen groups are optionally substituted with one or more fluorine atoms; R 3 and R 4 independently represent hydrogen, C 1-3 alkyl and —C 1-3 alkyl-O—C 1-3 alkyl which latter three groups are optionally substituted with one or more fluorine atoms, with the proviso that R 3 and R 4 both are not hydrogen; or R 3 and R 4 if both are attached to the same carbon atom, they may together with the carbon atom to which they are attached form a ring selected from the group consisting of cyclopropyl, cyclobutyl, cyclopentyl, and cyclohexyl, which groups are optionally substituted with one or more fluorine atoms; R 5 and R 6 independently represent hydrogen, C 1-5 alkyl, benzyl, —C(O)—C 1-5 alkyl, —C(S)—C 1-5 alkyl and —S(O) 2 —C 1-5 alkyl which latter five groups are optionally substituted with one or more fluorine atoms, or R 5 and R 6 together with the nitrogen atom to which they are attached form a 4-6-membered heterocyclyl ring optionally substituted with one or more fluorine atoms; Q represents CH or N; or a physiologically acceptable salt thereof.
