5,5-Dimethyl-2,4-imidazolidinedithione → HCID 178418313, compound

Participants

Reaction Steps

Initially, 11 g of 2-dimethylaminobenzylchloride hydrochloride was added to a solution of 8 g of 5,5-dimethyl-2,4-dithiohydantoin in 200 mL of chloroform (CHCl3) at about 60° C. The reaction mixture was stirred for 30 minutes and washed with an aqueous solution of NaHCO3, dried over MgSO4, and concentrated in vacuo. The residue was treated following the procedure used for the compound (a). As a result, the desired compound of 2-(2-dimethylaminobenzylthio)-5,5-dimethylimidazolin-4-thione was isolated by column chromatography. The yield of this compound was 9.1 g with a yield ratio of 62.1%. Further, the desired compound of 2,4-bis(2-dimethylaminobenzylthio)-5,5-dimethyl-5H-imidazole was isolated. The yield of this compound was 1.2 g with a yield ratio of 5.6%.
