g 4-Methoxy-7-morpholin-4-yl-benzothiazole-2-carbothioic acid amide and 20.3 ml iodomethane in 100 ml tetrahydrofurane were stirred at room temperature for three days. The resulting precipitate was filtered to yield 0.74 g (51%) 4-methoxy-7-morpholin-4-yl-benzothiazole-2-carboximidothioic acid methyl ester hydroiodide; M.p.: 169–171° C.; MS (ISP): m/e=324 (M+H+).
