实验过程

By the procedure of Example 1, using 3-hydroxymethylpyridazine, the intermediate 3-[(2-aminoethyl)thiomethyl]pyridazine dipicrate, m.p. 145°-148° is prepared. Converting this picrate to the dihydrobromide, then to the free base by the procedure of Example 1 and reacting the 3-[(2-aminoethyl)thiomethyl]pyridazine with S-methylsiothiouronium sulphate by the procedure of Example 1 gives the title compound.
