Abstract
The present invention is comprised of improved methods in the preparation of oxazoles which results in higher yields with less impurities and contaminants. Oxazoles constitute valuable intermediates in the synthesis of pharmaceutically active substances such as, for example peroxisome proliferator activated receptor (PPAR) agonists which are pharmaceutical actives which can have a positive influence on both lipid and glucose metabolism.
