A convenient route to functionalized 3-amino-6-bromofuro[3,2-b]pyridine-2-carboxamides

An efficient synthesis of 3-amino-6-bromofuro[3,2-b]pyridine-2-carboxamides is described via the formation of 3-amino-6-bromofuro[3,2-b]pyridine-2-carbonitrile. Functionalization of the amino group at position 3 of the heterocycle will be discussed.
