Reaction Steps

1-Benzyl-2-thiohydantoin (8.07 g), iodomethane (10 ml) and methanol (50 ml) were warmed at 40°-42° C. for 8 hours. The reaction mixture was evaporated under reduced pressure, the residue was washed with diethyl ether and recrystallised from methanol-ethanol to give 1-benzyl-2-methylthio-2-imidazolin-4-one hydroiodide (4.86 g) m.p. 185°-190° C., as an impure light-buff coloured solid which was taken on to the next stage.
