The present invention relates to certain novel benzylamine derivatives of formula (I) wherein R and R, which may be the same or different, are each selected from C6-12aryl, C2-14heteroaryl, C6-12arylC1-6alkyl, C2-14heteroarylC1-6alkyl (where the alkyl, aryl or heteroaryl moiety may be optionally substituted by one or more substituents selected from C1-6alkoxy, C1-6alkyl, C3-6cycloalkyl, C4-6cycloalkenyl, C6-12aryl, C2-14heteroaryl, halogen, amino, hydroxy, haloC1-6alkyl, nitro, C1-6alkylthio, sulphonamide, C1-6alkylsulphonyl, hydroxy-C1-6alkyl, C1-6alkoxycarbonyl, carboxyl, carboxyC1-6alkyl, carboxamide and C1-6alkylcarboxamide), hydrogen, C1-6alkyl, C3-6cycloalkyl, C4-6cycloalkenyl, C2-6alkenyl, C2-6alkynyl and C1-6alkoxyC1-6alkyl (where the alkyl, cycloalkyl, cycloalkenyl, alkenyl, alkynyl, or alkoxyalkyl moieties may be optionally substituted by one or more substituents selected from amino, halogen, hydroxy, C1-6alkylcarboxamide, carboxamide, carboxy, C1-6alkoxycarbonyl, C1-6alkylcarboxy and carboxyC1-6alkyl) or one of R and R are as hereinbefore defined and one is hydroxy; R and R, which may be the same or different, are each selected from C6-12aryl, C2-14heteroaryl, C6-12arylC1-6alkyl, C2-14heteroarylC1-6alkyl (where the alkyl, aryl or heteroaryl moiety may be optionally substituted by one or more substituents selected from C1-6alkoxy, C1-6alkyl, C3-6cycloalkyl, C4-6cycloalkenyl, C6-12aryl, C2-14heteroaryl, halogen, amino, hydroxy, haloC1-6alkyl, nitro, C1-6alkylthio, sulphonamide, C1-6alkylsulphonyl, hydroxyC1-6alkyl, C1-6alkoxycarbonyl, carboxyl, carboxyC1-6alkyl, C1-6alkylcarboxamide and carboxamide), hydrogen, C1-6alkyl, C3-6cycloalkyl, C3-6cycloalkylC1-6alkyl, C4-6cycloalkenyl, C2-6alkenyl, C2-6alkynyl, C1-6alkoxy-C1-6alkyl, haloC1-6alkyl, haloC2-6alkenyl, haloC2-6alkynyl, cyano, carboxyl, C1-6alkylcarboxy and carboxyC1-6alkyl (where the alkyl, cycloalkyl, cycloalkenyl, alkenyl, alkynyl, or alkoxyalkyl moieties may be optionally substituted by one or more substituents selected from amino, hydroxy, C1-6alkylcarboxamide, carboxamide, carboxy, C1-6alkoxycarbonyl, C1-6alkylcarboxy and carboxyC1-6alkyl); or one of R or R together with one of R or R and the N atom to which it is attached form a 5- or 6-membered heterocyclic ring. R represents one or more ring substituents selected from halogen, hydrogen C1-6alkyl and C1-6alkoxy; and R represents a single ring substituent of formula (A) wherein the dotted line represents an optional bond; Y is oxygen or -NR (where R is hydrogen or C1-6alkyl) and R represents one or more substituents selected from hydrogen, halogen, haloC1-6alkyl, C1-6alkyl and C1-6alkoxy; or a pharmaceutically acceptable salt or solvate thereof. The invention also relates to processes for their preparation, to pharmaceutical formulations containing them and to their use in medical therapy, particularly in the treatment of depression.
