A method for the modular synthesis of α-heteroaryl piperidines is reported. The two-step procedure consists of an initial Pd-catalyzed Suzuki cross-coupling of the heteroaryl bromide with a boronate ester derived from N-Boc piperidone, followed by subsequent tetrahydropyridine reduction. Using this method, α-heteroaryl piperidine products featuring a broad range of pharmaceutically relevant azine and diazine substitutions have been prepared.
