Procedure
When a solution of 3,4-dimethoxy-1,2,5-thiadiazole 1-oxide [prepared in Example 4, Step A] is successively reacted with an equimolar amount of 2-[(5-dimethylaminomethyl-2-thienyl)methylthio]ethylamine and excess ethylamine according to the procedure described in Example 18, the title compound is thereby produced.
