The present invention is directed to alkoxy tetrahydro-pyridopyrimidine compounds which are useful as therapeutic agents for the treatment of central nervous system disorders associated with phosphodiesterase 10 (PDE10). The present invention also relates to the use of such compounds for treating neurological and psychiatric disorders, such as schizophrenia, psychosis or Huntington's disease, and those associated with striatal hypofunction or basal ganglia dysfunction.

A weak antagonist of the pyrimidinergic receptor P2Y(14) containing a dihydropyridopyrimidine core was identified through high-throughput screening. Subsequent optimization led to potent, non-UTP competitive antagonists and represent the first reported non-nucleotide antagonists of this receptor. Compound 18q was identified as a 10 nM P2Y(14) antagonist with good oral bioavailability and provided sufficient exposure in mice to be used as a tool for future in vivo studies.
