The present invention is directed to aryloxymethyl cyclopropane derivatives 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.

1,3,5-Trisubstituted pyrazoles were found to be suitable partners for palladium-catalyzed directarylation via C-H activation/functionalization using aryl bromides. The reaction conditions and the catalyst have a determining influence on the yields. The systemusing palladium(II) acetate as the catalyst, potassium acetate as the base, and N,N-dimethylacetamide as the solvent promotes selective 4-arylations
