0.08 g of 1H-Imidazole-2-carbothioic acid (2-methoxy-5-morpholin-4-yl-phenyl)-amide (0.25 mmol) were taken up in water (2.0 ml) and treated with 0.056 g KOH (1.0 mmol) and 0.331 g of potassium hexacyano ferrate (1.0 mmol) at reflux for 1 h. After cooling to ambient temperature water (10 ml) was added and the mixture was filtered. The residue on the filter was dried in vacuo at 40° C. One obtained 0.037 g of 2-(1H-imidazol-2-yl)-4-methoxy-7-morpholin-4-yl-benzothiazole (47%) as a yellow solid; M.p.: 228–230° C.
