## Abstract magnified image The reaction of __N__‐methyl‐ (**3a**) or __N__‐phenylcyanothioformamide (**3b****)** with acetaldimine (**5a**, as 1‐amino‐1‐ethanol) gives 5‐(amino)imidazolidine‐4‐thiones **6B**. Product **6a** reacts with a second equivalent of **3a** to give **8** which in turn is o
