Participants

Reaction Steps

Reaction of methylphenylsulfone with carbon disulphide under strongly basic conditions and treatment of the product with methyl iodide yields 1-benzenesulphonyl-2,2-bis(methylthio)ethylene. When 1-benzenesulfonyl-2,2-bis(methylthio)ethylene is reacted with 2-[(4-methyl-1H-imidazol-5-yl)-methylthio]ethylamine according to the procedure of Example 6, Step A, the product is 1-benzenesulfonyl-2-methylthio-2-{2-[(4-methyl-1H-imidazol-5-yl)methylthio]ethylamino}ethylene. Reaction of this methylthio compound with propargylamine by the procedure of Example 6, Step B, yields the title compound.
