improved oral bioavailability, metabolic stability, and pharmacokinetic properties, lower molecular weight, structurallysimpler piperidine and piperazine analogs of BMS-694153 were prepared. Several were found to have nM binding affinity in vitro. The synthesis and SAR of these substituted piperidine and piperazine CGRP antagonists are discussed.
The present invention relates to a process to produce compounds of the formula (1) which are suitable for use in electronic devices, as well as to intermediate compounds of formula (Int-1) and compounds of formula (1-1) and (1-2) obtained via the process. These compounds are particularly suitable for use organic electroluminescent devices. The present invention also relate to electronic devices, which comprise these compounds.
