Versuchsvorschrift

A mixture of 5-(N'-benzoylthiocarbamoyl)amino-1-(3-benzyloxyprop-1-oxy)imidazole-4-carboxamide (2.9 g, 6.4 mmol), 0.1N sodium hydroxide solution (100 ml) and methyl iodide (0.64 ml; 10.3 mmol) was stirred at 20° C. for 16 hours and then the solution adjusted to pH 5 with glacial acetic acid. After several extractions with chloroform, the combined extracts were dried (magnesium sulphate) and evaporated to a syrup. Column chromatography on silica gel (eluted with chloroformethanol, 30:1) afforded the title compound (2.7 g, 88.7%).
