摘要: The present invention is generally directed to a process to directly prepare pharmaceutically acceptable salts enriched with respect to selected rotameric salts of a basic compound, by creative choice of an acid and a solvent medium. The process is particularly useful in preparing specific rotamers of pharmaceutically useful salts in desired preponderance of a rotamer.

摘要: The present invention relates to an improved process for preparing himbacine analogs. The compounds are useful as thrombin receptor antagonists. The improved process may allow for at least one of easier purification by crystallization, easier scalability, and improved process yield on the desired enantiomer. An example of a step in the synthesis of such a himbacine analog is as follows:
