反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 5-methyl-2-thiohydantoin (15 g.) and methyl iodide (16.3 g.) in dry ethanol (130 ml.) was heated under reflux for 11/2 hours, and then allowed to stand at 0° overnight. The crystalline product was filtered and washed with ether to give 2-methylthio-5-methyl-2-imidazolin-4-one hydroiodide (17.8 g.), m.p. 170°-173°. under reflux for 11/2 hours The crystalline product was filtered washed with ether
