Magnetic graphene oxide functionalized with sulfonic acid (Fe 3 O 4 ‐GO‐SO 3 H) was used as a new recyclable nanocatalyst for one‐pot synthesis of N‐aryl‐2‐amino‐1,6‐naphthyridine derivatives under solvent free conditions. The catalyst could be easily recovered from the reaction mixture by an external magnet and reused without significant decrease in activity even after 4 runs. This nanocatalyst exhibited better activities to other commercially available sulfonic acid catalysts.
