Compounds of the formula ##STR1## wherein R.sup.1 to R.sup.4 each are hydrogen, hydroxy, halogen, lower alkyl, lower alkoxy or phenyl; R.sup.5 is hydrogen or lower alkyl, R.sup.6 is hydrogen, lower alkyl or lower alkoxy; X is --(CR.sup.7 R.sup.8).sub.n -- or --CH.dbd.CH--; R.sup.7 and R.sup.8 are hydrogen or lower alkyl and n is 1 or 2, as well as pharmaceutically acceptable salts of basic compounds of formula I, bind to serotonin receptors, and thus are useful in treating central nervous system disorders.
The invention pertains to heteroaromatic compounds that serve as effective phosphodiesterase (PDE) inhibitors. In particular, the invention relates to said compounds which are selective inhibitors of PDE10. The invention also relates to intermediates for preparation of said compounds; pharmaceutical compositions comprising said compounds; and the use of said compounds in a method for treating certain central nervous system (CNS) or other disorders.

single-digit nanomolar activity in the mGlu2 NAM GTPγS assay. In addition to SAR on in vitro potency, a more detailed overview is given with a specific set of compounds on the excellent agreement between in vitro potency, free brain concentration, and exvivo mGlu2 receptor occupancy. Finally, to obtain improved drug-like compounds, plans for future research are suggested towardincreasing free brain concentration
