Patent ID: 8648099

Claim:
The compound according to formula I, wherein R 1 is selected from the group consisting of C 3-7 -cycloalkyl, C 3-7 -cycloalkyl-C 1-7 -alkyl, and halogen-C 1-7 -alkyl; R 2 is selected from the group consisting of phenyl, said phenyl being unsubstituted or substituted by one, two or three groups selected from the group consisting of C 1-7 -alkyl, C 1-7 -alkoxy, halogen, halogen-C 1-7 -alkyl, halogen-C 1-7 -alkoxy, amino, azido and cyano, C 3-7 -cycloalkyl, furyl, and heterocyclyl, said heterocyclyl having 3 to 7 ring atoms, comprising one, two or three heteroatoms selected from N, O and S and being unsubstituted or substituted by a C 1-7 -alkoxycarbonyl group; R 3 is hydrogen; R 4 is hydrogen or C 1-7 -alkyl; or R 3 and R 4 are —(CH 2 ) 3 — and together with the nitrogen atoms to which they are attached form a 5-membered heterocyclic ring; and R 5 is selected from the group consisting of hydrogen, halogen-C 1-7 -alkyl, hydroxyl-C 1-7 -alkyl, C 1-7 -alkoxycarbonyl, phenyl, said phenyl being unsubstituted or substituted by one, two or three groups selected from the group consisting of C 1-7 -alkyl, halogen, halogen-C 1-7 -alkyl and cyano, heteroaryl, said heteroaryl being unsubstituted or substituted by one or two groups selected from the group consisting of C 1-7 -alkyl, halogen and halogen-C 1-7 -alkyl; and heteroaryl-C 1-7 -alkyl, said heteroaryl-C 1-7 -alkyl being unsubstituted or substituted by one or two groups selected from the group consisting of C 1-7 -alkyl, halogen and halogen-C 1-7 -alkyl; or R 4 and R 5 together with the nitrogen atom to which they are attached form a 4-, 5-, 6- or 7-membered heterocyclic ring optionally containing a further heteroatom or group selected from nitrogen, oxygen, sulfur, sulfinyl and sulfonyl, said heterocyclic ring being unsubstituted or substituted by one, two or three groups independently selected from C 1-7 -alkyl, hydroxy, oxo, hydroxy-C 1-7 -alkyl, C 1-7 -alkoxy, C 1-7 -alkoxy-C 1-7 -alkyl, heterocyclyl-C 1-7 -alkyl, C 1-7 -alkylcarbonyl and C 1-7 -alkylsulfonyl; or a pharmaceutically acceptable salt thereof.
