Participants

Reaction Steps

To S-methylisothiourea sulfate (8.35 g, 30.0 mmol), 1 M sodium hydroxide aqueous solution (60 mL) was added and then 1,1′-carbonyldiimidazole (9.73 g, 60.0 mmol) was slowly added at 0° C. with stirring, followed by stirring the resultant mixture at 0° C. for 30 minutes. After completion of the reaction, the precipitated solid was collected by filtration and the obtained solid was washed with ice water and dried to obtain the title compound (7.89 g, yield 72%).
