                                    A simple, efficient, and mild protocol for the synthesis of 4‐naphthylpyrimidin‐2‐amine derivatives under solvent‐free conditions by the reaction of aromatic aldehydes (or 1‐naphthaldehyde), 2‐acetylnaphthalene (or aromatic ketones), guanidine carbonate, and sodium hydroxide was reported. The advantages of this protocol include short reaction time, mild reaction conditions, easy workup, high yields, and environmental friendliness.
