Procedure

2-Mercaptoimidazole (24.39 g, 0.244 mole) and butyl isocyanate (48.3 g, 0.487 mole) were combined in a round-bottom flask and heated to 50° C. for 30 min or until the reaction was complete by TLC. The reaction mixture was then cooled to room temperature and the solidified mass was triturated with 50 mL of hexane for 30 min. The beige solid was filtered, washed with a minimum amount of hexane and dried under reduced pressure to yield 44.96 g (93%) of 1-(butylcarbamoyl)-1,3-dihydroimidazole-2-thione as beige crystals: mp 66°-68° C.
