4-aminoalkoxy-1,3-dihydrobenzoimidazol-2-one derivatives, their preparation and their use as dopamine autoreceptor (d2) agonists

摘要

Disclosed are compounds of formula (I), wherein R<1> is hydrogen or C1-C6 alkyl; R<2> is selected from hydrogen, straight-chain and branched C1-C10 alkyl, cyclohexylmethyl or -(CH2)mAr where Ar is phenyl, naphthyl, thienyl, furanyl or pyridinyl, each optionally substituted by one or two substituents selected independently from C1-C6 alkyl, halogen, C1-C6 alkoxy and trifluoromethyl; or NR<1>R<2> is 1,2,3,4-tetrahydroquinolin-1-yl or 1,2,3,4-tetrahydroisoquinolin-2-yl; m is 1-5; n is 1 or 2; R<3> is hydrogen or C1-C6 alkyl; Y is halogen, C1-C6 alkyl, and C1-C6 alkoxy; or a pharmaceutically acceptable salt thereof, which are dopamine autoreceptor agonists and as such are useful in the treatment of schizophrenia, Parkinson's disease, Tourette's syndrome, alcohol addiction and drug addiction.
