    • The present invention relates to a group of novel benzisoxazole derivatives which are potent and selective antagonists of the dopamine D4-receptor. The compounds have general formula (I) wherein (R1)n represents 0, 1, or 2 substituents, which can be the same or different, from the group C1-3-alkyl or alkoxy, halogen, trifluoromethyl, nitro, amino mono- or dialkyl (C1-2)-amino, sulfonyl-(C1-3)alkyl or -alkoxy, sulfonyl trifluoromethyl, sulfonyl amino, and sulfonyl mono- or dialkyl (C1-2)-amino, X is O, S, NH or NCH3, Y represents CH2, or (CH2)2, (R2)m represents 0, 1, or 2 substituents, which can be the same or different, from the group methyl and ethyl, or (R2)m is a methylene bridge or ethylene bridge, A is a group —CH2—(CRH)p— wherein R is hydrogen or methyl and p is 0 or 1, and B represents 2- or 3-indolyl or 2-benzimidazolyl, which groups may be substituted at carbon with 1 or 2 substituents from the group C-1-3-alkyl or alkoxy, halogen, trifluoromethyl, nitro, amino, mono- or dialkyl (C1-2)amino, sulfonyl-(C1-3)alkyl or -alkoxy, sulfonyl trifluoromethyl, sulfonyl amino, and sulfonyl mono- or dialkyl (C1-2)-amino.
