A continuous Buchwald–Hartwig reaction using the bulky N-heterocyclic carbene (NHC) precatalyst [Pd(IPr*)(cin)Cl] 4 has been developed for the synthesis of a key pharmaceutical intermediate 2. Using microreactor technology, the reaction could be optimized under dilute conditions with low material...
