1‐Aminopyrimidine‐2‐one derivatives (1a‐c) were prepared in two steps from furan‐2,3‐diones and semicarbazones in toluene/benzene. Pyrimidin‐[1(2H)‐yl] acetamide derivatives and isophthalimide derivatives were synthesized from the nucleophilic acyl substitution reactions of compounds 1a‐c with chloroacetyl chloride. The structures of compounds 2a‐f were verified by IR, 1H NMR, 13C NMR and elemental...
