We report herein a high-temperature and high-pressure continuous-flow protocol to carry out nucleophilic aromatic substitution (SNAr) of heterocycles with nitrogen nucleophiles. Utilizing the Phoenix Flow Reactor in parallel with Design-of-Experiment software enabled rapid optimization of the SNAr protocol. This protocol facilitated efficient synthesis of a broad range of 2-aminoquinazolines, and was extended to 2-aminoquinoxalines and 2-aminobenzimidazoles.
