Versuchsvorschrift
Reaction of a methanolic solution of 3,4-dimethoxy-1,2,5-thiadizole 1-oxide [prepared in Example 4, Step A] with one equivalent of methylamine and treatment of the resultant 3-methoxy-4-methylamino-1,2,5-thiadiazole 1-oxide with one equivalent of 2-[(5-dimethylaminomethyl-2-furyl)methylthio]ethylamine yields the title compound, which is identical to the product prepared in Example 18.
