Reaction Steps

4-{[Ethyl-(4-methoxy-pyrimidin-2-yl)-amino]-methyl}-imidazole-1-sulfonic acid dimethylamide (0.265 g, 0.78 mmol) was dissolved in aqueous hydrochloric acid (4 N, 2 ml) and the mixture was stirred at 100° C. for 2 hours. After cooling concentrated sodium hydroxide solution was added slowly until basic pH. The mixture was extracted three times with ethyl acetate. The combined organic layers were dried over magnesium sulfate and evaporated. The residue was purified by flash chromatography, column: Isolute® Flash-NH2 (Separtis); eluent: heptane/ethyl acetate=1:1) to yield a colorless liquid, (0.10 g, 55%); MS (ISP): 234.3 ((M+H)+.).
