Reaction Steps
To a well stirred suspension of 3,4-dimethoxy-1,2,5-thiadiazole 1,1-dioxide (2.0 g; 11.2 mmoles) [prepared according to the procedure described in J. Org. Chem., 40, 2743 (1975)] in 200 ml of methanol at ambient temperature was added a solution of 2-[(5-methyl-1H-imidazol-4-yl)methylthio]ethylamine (from the dihydrochloride, 2.73 g; 11.2 mmoles) [prepared according to Belgian Pat. No. 779,775] in 25 ml of methanol. After stirring for 30 minutes, a methanolic solution of the title compound was produced. The TLC (Silica/CH2Cl2 :CH3OH (90:10)] gave Rf=0.44.
