Diverse 2-carboxamide-3-amino-substituted quinoxalines: synthesis and reactivity investigation for library generation.

Described herein is the development of a robust synthetic route applicable to parallel synthesis of diverse 2-carboxamide-3-amino-substituted quinoxalines. In addition to the scope and limitations of the methods developed, a purification strategy employing solid-phase extraction (SPE) and application of the methods to a small parallel array of compounds are discussed.
