摘要:
The invention provides compounds of formula (I) wherein R1 is C1-6alkyl, halo or haloC1-6alkyl; R2 is hydrogen or C1-6alkyl; ===== is a single or double bond; each R3 and R4, which may be the same or different, are hydrogen, C1-6alkyl or haloC1-6alkyl; wherein i) when ===== is a double bond p and q are 1, and ii) when ===== is a single bond, p and q are 2, and one of R3 and one of R4 together with their interconnecting atoms, forms a cyclopropane ring which may be substituted by one or two halo or methyl groups, which groups may be the same or different; X is CH or N; when present each R5, which may be the same or different, is C1-6alkyl or halo; or two R5 groups may join to form a bridge, which bridge contains one or two atoms; n is 0, 1, 2 or 3; when present each R6 which may be the same or different, is C1-6alkyl or halo; and m is 0, 1, 2 or 3.
摘要:
The invention provides a compound of formula (I) or a pharmaceutically acceptable salt thereof for treating diseases and conditions mediated by positive allosteric modulation of the G- protein coupled metabotropic subtype 5 receptor (mGluR5), such as neurological and psychiatric disorders, for example schizophrenia. In addition, the invention relates to compositions containing the derivatives and processes for their preparation.
