coupling of the amino terminus of d-phenylalanine methylester to the free 5′-carboxylic acid moiety of 33 followed by sodium hydroxide treatment led to carboxylic acid analog 77. Hydrolysis of this material gave analog 78. The intermediate 77 served as the precursor for the preparation of novel dipeptidyl uridine analogs 79–99 through peptide coupling reactions to diverse amine reactants. None of the described

NIH Roadmap Initiative and the Pilot Scale Library (PSL) Program. Reaction core compounds contained -NH2 (2) and -COOH (44 and 93) groups that were coupled to a diversity of reactants in a parallel, solutionphase format to produce the target library. The assorted reactants included -NH2, -CHO, -SO2Cl, and -COOH functional groups, and condensation with the intermediate core materials 2 and 44 followed
[Problem] A compound which is useful as a dopamine D1 receptor positive allosteric modulator (D1 PAM) is provided.
[Means for Solution] The present inventors have studied a compound which has a dopamine D1 receptor positive allosteric modulating activity and is useful as an active ingredient of a pharmaceutical composition for preventing and/or treating cognitive impairment, negative symptoms of schizophrenia, Parkinson's disease, Alzheimer's disease, Huntington's disease, drug addictions, or the like, and they have thus found that a heterocyclic acetamide compound has a dopamine D1 receptor positive allosteric modulating activity, thereby completing the present invention. The heterocyclic acetamide compound of the present invention has a dopamine D1 receptor positive allosteric modulating activity and can be used as an agent for preventing and/or treating cognitive impairment, negative symptoms of schizophrenia, Parkinson's disease, Alzheimer's disease, Huntington's disease, drug addictions, or the like.

A smalllibrary of fifty-five adenosine peptide analogs was synthesized, under the Pilot Scale Library (PSL) Program of the NIH Roadmap initiative, from 2′,3′-O-isopropylideneadenosine-5′-carboxylic acid 2. The coupling of amine or sulfanilamide reactants to the free 5′-carboxylic acid moiety of 2, in automated solution-phase fashion, led after acid-mediated hydrolysis to target compounds 3–57 in good
