Abstract
There is provided a method to convert O-functionalized indazolinone-derivatives to the corresponding N2-functionalized indazolinone derivatives, by use of microwave energy or a transition metal catalyst. A preferred catalyst is palladium tetrakis. The method described allows the creation of a library of chemical compounds which can be screened for biological activity.
