Versuchsvorschrift

A mixture of the isothiourea dihydrochloride of Example 1 (i) (6.7 g), N-methyl-N-tert-butoxycarbonylhydrazine sulphate (5.7 g), potassium hydrogen carbonate (10.0 g) and anhydrous dimethylformamide (80 ml) was stirred at 90° C. for 3 hours. After cooling, filtration and concentration to yield the free base, this was heated under reflux with ethanolic hydrogen chloride. Concentration and trituration of the residual product yielded the title compound.
