Reaction Steps

Reaction of a methanolic suspension of 3,4-dimethoxy-1,2,5-thiadiazole 1,1-dioxide with one equivalent of ethylamine and treatment of the resultant 3-methoxy-4-ethylamino-1,2,5-thiadiazole 1,1-dioxide with one equivalent of 2-[(5-dimethylaminomethyl-2-furyl)methylthio]ethylamine yields the title compound, which is identical to the product prepared in Example 12.
