A method for palladium‐catalyzed direct arylation has been developed for the selective functionalization of the C‐3 and C‐7 positions of 2‐substituted furo[3,2‐ b ]pyridines. An unconventional reactivity resulting from the annulation of a pyridine ring with a furan ring is outlined and results in an unprecedented C‐7H bond activation. The role of the pivalic acid additive is rationalized by invoking a concerted metallation–deprotonation pathway (CMD) for both arylations.
