The reaction of methyl 3‐aryl‐2‐cyano‐3‐methoxypropenoates 1 with cyanamide and sodium methoxide in methanol afforded after acid hydrolysis the methyl 3‐[(aminocarbonyl)amino]‐3‐aryl‐2‐cyanopropenoates 4 . By performing the reaction in higher boiling alcohols the 2‐alkoxy‐6‐aryl‐5‐cyano‐4(3 H )‐pyrimidinones 2 were obtained in good yields.
