Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 16263-52-8, Name is 3-Chloro-1,2-benzisoxazole,introducing its new discovery., SDS of cas: 16263-52-8
BENZISOXAZOLE DERIVATIVES HAVING D4-ANTAGONISTIC ACTIVITY
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 (R 1) n represents 0, 1, or 2 substituents, which can be the same or different, from the group C 1-3-alkyl or alkoxy, halogen, trifluoromethyl, nitro, amino mono-or dialkyl (C 1-2)-amino, sulfonyl-(C 1-3)alkyl or-alkoxy, sulfonyl trifluoromethyl, sulfonyl amino, and sulfonyl mono-or dialkyl (C 1-2)-amino, X is O, S, NH or NCH 3, Y represents CH 2, or (CH 2) 2, (R 2) m represents 0, 1, or 2 substituents, which can be the same or different, from the group methyl and ethyl, or (R 2) mis a methylene bridge or ethylene bridge, A is a group–CH 2–(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 (C 1-2)amino, sulfonyl-(C 1-3)alkyl or-alkoxy, sulfonyl trifluoromethyl, sulfonyl amino, and sulfonyl mono-or dialkyl (C 1-2)-amino.
