## Abstract 2‐Alkylthio‐3‐amino‐4H‐imidazol‐4‐ ones **5** were synthesized by S‐alkylation of 2‐thioxo‐3‐amino‐4‐imidazolidinones **4**, which were obtained via cyclization of isothiocyanates **2** with hydrazine hydrate. **5l–n** reacted with Ph~3~P, C~2~Cl~6~, and NEt~3~ to give 2H‐imidazo[2,1‐b]
