Claim:
A compound of the formula wherein X is C—R 6 ; R 1 is hydrogen or lower alkyl; R 2 is selected from the group consisting of lower alkyl which is unsubstituted or substituted by one, two or three groups independently selected from the group consisting of hydroxy, lower alkoxy, fluorinated lower alkyl, fluorinated lower alkoxy, phenyl, cycloalkyl and a 5- or 6-membered saturated heterocyclic ring containing one or two heteroatoms independently selected from nitrogen and oxygen; fluorinated lower alkyl; cycloalkyl which is unsubstituted or substituted by one, two, three or four groups independently selected from the group consisting of hydroxy, lower alkyl, lower alkoxy, fluorinated lower alkyl and fluorinated lower alkoxy; a 5- or 6-membered saturated heterocyclic ring containing one or two heteroatoms independently selected from nitrogen and oxygen, said heterocyclic ring being unsubstituted or substituted by one, two or three groups independently selected from the group consisting of hydroxy, lower alkyl, lower alkoxy, amino, lower alkylamino, oxo, fluorinated lower alkyl and fluorinated lower alkoxy; bicyclo[4.1.0]hept-7-yl which is unsubstituted or substituted by one, two or three groups independently selected from the group consisting of lower alkyl, hydroxy and lower alkoxy, or is condensed with a phenyl ring; and 4,7,7-trimethylbicyclo[2.2.1]hept-2-yl which is unsubstituted or substituted by one, two or three groups independently selected from the group consisting of hydroxy, lower alkoxy and lower acyloxy; R 3 is a 5- or 6-membered saturated heterocyclic ring containing one or two oxygen atoms, said heterocyclic ring being unsubstituted or substituted by one, two or three lower alkyl groups, or being condensed with a phenyl ring or R 3 is a pyrrolidine ring being unsubstituted or substituted by lower alkyl or alkoxycarbonyl; R 4 is phenyl, unsubstituted or substituted by one, two or three groups independently selected from the group consisting of hydroxy, lower alkyl, lower alkoxy, halogen, halogenated lower alkyl and halogenated lower alkoxy; R 5 is selected from the group consisting of hydrogen, lower alkyl and lower alkoxyalkyl; R 6 is hydrogen or lower alkyl; m is 1 or 2; and pharmaceutically acceptable salts thereof.
